The Origin Of Classical Yog
In the 3rd century BCE, the great sage Patanjali reviewed and compiled the many yog practices that had been developed and tested by the ancient yogis of India. He brought clarity to the purpose of yog, defined its techniques, and organized them into a structured and progressive system. After evolving through countless streams of Indian spiritual and philosophical thought, yog was finally shaped into a clear, scientific discipline known today as Classical Yog.
Patanjali’s Yog Sutras are considered a timeless classic. This text has endured through centuries, serving as the most reliable and practical guide for those committed to deeper and more structured yog practice.
Patanjali defined yog as a disciplined path involving eight core practices:
यम-नियम-आसन-प्राणायाम-प्रत्याहार-धारणा-ध्यान-समाधयोऽष्टावङ्गानि ॥
-
Yam – Five moral restraints (ethical principles)
-
Niyam – Five observances or personal disciplines
-
Asan – The practice of physical postures
-
Pranayam – Breath control techniques
-
Pratyahar – Withdrawal of the senses from external objects
-
Dharana – Concentration or focused attention
-
Dhyan – Meditation
-
Samadhi – A state of deep absorption or spiritual enlightenment
This eight-part system is known as Ashtang Yog, meaning “the eightfold path.” The ultimate aim of Ashtang Yog is to realize the inner Spirit. Each stage is designed to gradually purify the body and mind, enabling the practitioner to turn inward and connect with their true self.
Ashtang Yog is typically divided into three main categories of spiritual practice:
-
Yam and Niyam form the ethical foundation, guiding behavior and cultivating the virtues necessary for spiritual growth.
-
Asan, Pranayam, and Pratyahar are known as Bahirang or external practices, which together make up Hatha Yog. These focus on physical discipline, enhancing strength, vitality, and mental calmness.
-
Dharana, Dhyan, and Samadhi make up Raj Yog, the Antarang or internal practices. Raj Yog emphasizes deep concentration and meditation, leading to Samadhi, the ultimate state of super-consciousness and inner peace.
The Levels of Ashtang Yog
Ashtang Yoga, meaning the “Eightfold Path,” is a systematic approach to spiritual growth outlined by the sage Patanjali. It consists of eight progressive stages designed to guide practitioners from outer discipline to inner awakening.
The first two stages, Yam and Niyam, focus on ethical living—moral restraints like non-violence and truthfulness, and personal observances such as purity and contentment. These create a strong foundation for spiritual practice by purifying the mind and behavior.
The next stages involve physical and mental preparation: Asan (yoga postures) strengthens and steadies the body, while Pranayam (breath control) helps regulate energy and calm the mind. Pratyahar teaches the withdrawal of the senses from external distractions, enabling the practitioner to turn inward.
This leads to Dharana (concentration), where the mind focuses on a single point and Dhyan (meditation), a deep, sustained state of awareness. The final stage, Samadhi, is the state of spiritual enlightenment or union with the higher self, where the practitioner experiences inner peace and bliss. Together, these eight limbs of Ashtang Yog offer a complete path to harmonize body, mind, and spirit for lasting self-realization.
Let us now explore each of these eight levels in detail to understand better how they guide us step-by-step toward spiritual growth and inner peace. By learning about the purpose and practice of each limb, we can apply them effectively in our own yoga journey.
1. Yam And Niyam : Foundations of Self-Discipline
Anyone seeking spiritual enlightenment must begin by purifying the body, mind, and heart — the threefold dwelling place of the Spirit. The first two limbs of Yog, Yam and Niyam, serve this purpose by laying down a foundation of ethical and moral conduct. These principles promote truthfulness, love, celibacy, honesty, simplicity, self-discipline, and devotion to God.
Yam refers to self-restraints, while Niyam refers to personal observances. Together, they help the practitioner control emotions and desires that typically disrupt inner peace. To truly know God and progress on the path of Yog, one must consistently follow Yam and Niyam.
In his Yog Darshan, Sage Patanjali defines five self-restraints (Yam):
Ahimsa – Non-violence or unconditional love for all beings
Satya – Truthfulness in thought, speech, and action
Astey – Non-stealing or cultivating honesty
Brahmacharya – Celibacy or self-restraint in desires
Aparigrah – Non-possessiveness or embracing a simple lifestyle
He also outlines five personal observances (Niyam):
Shauch – Cleanliness and purity
Santosh – Contentment and inner satisfaction
Tapas – Austerity and disciplined effort
Svadhyay – Self-study and study of spiritual texts
Ishvar Pranidhan – Surrender and devotion to God
Living without discipline and moral values inevitably results in unrest and suffering. Therefore, Yam and Niyam act as essential guidelines for those committed to a spiritual life. Their regular practice brings about peace, emotional balance, virtuous actions, and spiritual evolution. They represent the first — and enduring — step on the journey of Yog.
Yam and Niyam form the essential ethical foundation of yog, guiding us toward a balanced and harmonious life. These principles cover how we interact with the world and how we nurture ourselves internally. Because they are so rich and important, we’ve dedicated a full blog post to explore them in detail. If you’re curious to learn more about how practicing Yam and Niyam can transform your mindset, relationships, and overall well-being, be sure to check out that in-depth article! It’s packed with insights to help you embrace these timeless yogic values in your daily life.
2. Hath Yog : Harmony of Body and Mind.
Yogis believe that spiritual awakening can only be attained through the physical body, which should be regarded as the sacred temple of the inner Spirit. Consistent effort is necessary to make the body a more efficient vehicle for spiritual growth. A healthy mind dwells within a healthy body, and only when the mind is clear and the body is strong can one truly experience the realization of God. Without cleansing the body of impurities and maintaining its health, attempts to calm the mind and find peace will not succeed.
Hathyog is also known as Bahirang Yog because it primarily deals with the external aspects of the yogic path—those that involve the body and breath. The word “bahirang” means “external” or “outer”. In yog, purifying and controlling both the body and mind go hand in hand. Initially, physical discipline and bodily health take priority, but as one advances in practice, mental discipline becomes increasingly important.
As the practitioner’s character is refined through the ethical practices of Yam and Niyam, they should begin to engage in the foundational exercises of Hatha Yog: Asan (postures) and Pranayam (breath control). Asanas are physical movements aimed at restoring the body’s natural balance, while pranayama techniques purify the mind by regulating the breath. These practices cleanse both body and mind, strengthening internal systems.
The third and final element of Hatha Yog is Pratyahar, the withdrawal of the senses. This practice directs the mind inward, helping to detach from external desires and distractions. Pratyahar prepares the practitioner for true meditation and is essential for progressing to the higher stages of yog.
2.1 – Asan : The Foundation of Physical Stillness and Inner Harmony
Asan is the first level of Hathyog, whereas the third limb of Ashtang Yog.The Hatha Yog Pradipika states, “Asan is the foundational practice of Hatha Yog and should be the first to be mastered. It promotes steadiness, health, and lightness in the body.” Sage Patanjali describes Asan as “a steady and comfortable posture” (Yog Darshan 2:46). Achieving mastery over Asan, known as Asanjay, means attaining a continuous state of physical balance that is free from pain or discomfort.
When a yogi attains Asanjay, they are no longer disturbed by opposing natural forces such as heat and cold, strength and weakness—dualities that typically cause suffering. While overcoming such natural challenges may seem impossible, experienced yogis affirm that these can be conquered through dedicated yog practice. Mastery of Asan and Pranayam prepares the practitioner for meditation and paves the way for higher spiritual achievements.
It is said that one who cannot maintain a meditative posture for an extended time is not yet ready for advanced yog practices. Even Pranayam becomes fully effective only after mastering Asan. True Asanjay is achieved when an individual can remain steady and comfortable in a meditative posture for three hours without any discomfort. As noted in the Tejobindu Upanishad: “When Asan remains steady for three hours, it is adequate for yog practice.”
Mastering Asan is not easy. Beginners may struggle to hold postures steadily, and the difficulty varies with the complexity of the pose. Over time, however, maintaining the posture becomes effortless. This leads to a slowing of the vital energy (Prana), calming of the senses, and a peaceful mind.
Patanjali emphasizes “relaxation of effort” as the key to achieving a steady and comfortable posture. Each Asan involves slow, deliberate movements guiding the body into position. With regular practice, the posture becomes easy to hold, requiring minimal effort, and eventually becomes stable and comfortable for long durations.
The successful practice of Asan demands persistence and dedication. The Shandilya Upanishad proclaims, “One who conquers Asan will find victory in the three worlds.” These physical exercises build balance, strength, awareness, and inner tranquility. By focusing on effortless movement and relaxation, the mind uncovers deeper inner resources.
As one progresses, physical and mental capacities grow in harmony. This leads to an enhanced sense of unity and a rising awareness of the inner Spirit.
The practice of Asan, the third limb of Ashtang Yog, is explained in greater detail in dedicated blog article. That post highlights a variety of yog postures, their physical and mental benefits, and how they contribute to overall well-being. It also explores the relevance of Asans in today’s modern lifestyle, making it easier to understand their importance beyond just physical fitness.
2.2 – Pranayam : Mastering the Breath, Calming the Mind.
All great yogis agree that Asan lays the foundation upon which the deeper journey of Yog is built. Once stability in posture is attained, the practitioner is ready to explore the next vital step: Pranayam, or the conscious control of breath.
Pranayam purifies both the body and mind by cleansing the gross and subtle energy channels. This purification cultivates a calm and inward-focused state of mind, essential for deeper meditative practices. At first, the practitioner becomes aware of Pran —the life force— through the physical act of breathing. Over time, however, this awareness deepens, revealing Pran’s movement through the subtle energy channels of the astral body. Eventually, Pran is experienced as a spiritual energy capable of refining the intellect and uplifting the soul.
The disciplined practice of Pranayam leads naturally to Pratyahar, the withdrawal of the senses from external distractions. In this state, the mind detaches from sensory cravings and turns inward. Although worldly pleasures are often pursued in the hope of lasting happiness, they are temporary and can lead to dissatisfaction. Pranayam helps break this cycle by calming the mind, lessening attachment to sensory indulgence, and creating space for inner peace.
Only when desires subside can true contentment arise. With a mind free from turmoil and outward restlessness, one experiences true joy—one that comes from within, not from fleeting worldly experiences. Pranayam is the key to unlocking that inner bliss.
2.3 – Pratyahar : Withdrawing the Senses, Turning Inward
Pratyahar is the third and the final level of Hathyog, whereas the fifth limb of Ashtang Yog. The term is derived from two Sanskrit words: Prati meaning “against” or “in reverse,” and Ahar meaning “to take in” or “to gather.” Thus, Pratyahar means to withdraw or draw the senses inward, away from the external world.
In yogic practice, Pratyahar refers to the withdrawal of the mind from the five sense organs and their interaction with external objects. Rather than being absorbed in sights, sounds, smells, tastes, and touch, the mind turns inward, becoming more reflective and detached from sensory distractions.
To understand Pratyahar fully, one must grasp the intimate connection between the mind and the senses. The sense organs are passive tools; they only respond to external stimuli when the mind chooses to engage with them. At any moment, countless sounds and images surround us, but we only perceive those that our mind chooses to acknowledge. The rest pass unnoticed.
An untrained and outward-focused mind is constantly pulled by these sense impressions, leading to restlessness, emotional ups and downs, and mental confusion. Pratyahar trains the mind to detach from this stream of sensory input, promoting inner stillness and stability.
When mastered, Pratyahar prepares the mind for deeper meditation by reducing external distractions. It marks the completion of Hathyog and paves the way for the higher stages of Rajyog.
3. Rajyog : The Path to Union with the Supreme
Rajyog is also known as Antarang Yog, which means “inner” or “internal yog” because it focuses on the subtle, inward journey of the mind and consciousness. The final three limbs of Ashtang Yog —Dharana (concentration), Dhyan (meditation), and Samadhi (spiritual absorption)—together form what is known as Rajyog, the royal path of yog. These are the most advanced and subtle practices, designed to refine the aspirant’s discipline, purity, and spiritual focus, ultimately leading to the highest states of consciousness.
Only after mastering the practices of Hathyog does a seeker become truly prepared for Rajyog. As the Hathyog Pradipika declares, “All the techniques of Hathyog are practiced to achieve success in Rajyog.” It further states, “Through Asan, Pranayam, Mudras, and Pratyahar, one prepares for the ultimate goal Rajyog.” In this way, the entire journey of Ashtang Yog is seen as a process of purifying the body and mind in preparation for spiritual transcendence.
Among these stages, Pratyahar (withdrawal of the senses) serves as the gateway to the inner path. Without mastering Pratyahar, the attempt to control and focus the mind through concentration will inevitably falter. Even after sensory withdrawal, the mind still operates through the intellect, remaining confined to mundane perceptions.
Thus, the first two stages of Rajyog — Dharana and Dhyan — involve progressively deepening concentration. The third and ultimate stage, Samadhi, goes beyond the intellect and mental faculties. It is the domain of pure awareness—where consciousness merges with the universal, intuitive will. In Samadhi, the practitioner transcends all physical, mental, and emotional limitations, arriving at a state of perfect clarity, balance, and spiritual bliss.
3.1 – Dharana : The Art of Focused Concentration
Dharana is the first level of Rajyog, whereas the sixth limb of Ashtang Yog.
In Dharana, the mind is intentionally directed and held within a specific field of awareness, whether it be a chosen deity, a sacred symbol, an internal point within the body, or a subtle object of contemplation. The goal is to stabilize the mind and prevent it from wandering or becoming scattered.
At the beginning of this practice, the mind resists confinement, continuing its habitual tendencies toward distraction and mental chatter. However, with persistent effort, this restlessness gradually diminishes. The awareness begins to narrow and stabilize, allowing for deeper and more sustained focus.
Pratyahar, the withdrawal of the senses, is essential before true concentration can occur. Once the senses are turned inward and external distractions are minimized, the mind becomes more capable of remaining centered on a single point. As the practice of Dharana progresses, the power of concentration increases, and mental diffusion is brought under control.
Eventually, when all internal agitation ceases and the mind becomes fully absorbed in its object of focus, true Dharana is achieved. This unwavering concentration marks the threshold to the next stage of yog — Dhyan, or meditative absorption.
3.2 – Dhyan : The Flow of Unbroken Meditation
Dhyan is the second level of Rajyog, whereas the seventh limb of Ashtang Yog.
Dhyan is the practice of deep meditation marked by a continuous, unbroken stream of thought directed toward a single object — often the same deity, symbol, or inner focal point used in Dharana. Unlike Dharana, where the mind holds its attention with effort, Dhyan involves a natural and steady flow of concentrated awareness in one direction, undisturbed by distraction.
In this state, the mind is still active, but its movement is unique — it flows in a single, continuous channel, maintaining the same quality of thought throughout. There is no scattering, no deviation. If a distraction arises, the trained mind instinctively returns to its focus, resuming the contemplative stream with ease. This refined continuity marks the key distinction between Dharana (concentration) and Dhyan (meditation).
With sustained and sincere practice, the meditator eventually reaches the culmination of meditation — a point where the mind merges so completely with the object of contemplation that all mental activity ceases. The boundary between the perceiver and the perceived dissolves. The thinker, the thought, and the object of thought become one.
When this meditative absorption is complete, the act of Dhyan naturally transitions into the final stage of Ashtang Yoga — Samadhi, the ultimate state of spiritual union and transcendence.
3.3 – Samadhi : The Ultimate Union
Samadhi, is the third and the final level of Rajyog, whereas the eighth and final limb of Ashtang Yoga.
Samadhi is the state of perfect mental stillness and equanimity. It leads to total awareness or Super Consciousness, where the practitioner transcends all mental activity and becomes completely absorbed in the essence of Reality.
In Samadhi, the mind becomes entirely void of thoughts — even the awareness of the mind itself disappears. This is why it is often referred to as the state of the “non-mind.” While during Dhyan (meditation) the yogi may attain profound focus, there still remains a faint awareness of mental activity. This subtle sense of individuality and duality acts as a veil, keeping the seeker from directly experiencing the Absolute Truth.
But in Samadhi, that veil is lifted. The yogi’s self-awareness dissolves completely into the object of meditation. He sinks deep into the innermost core of consciousness, beyond time, space, and even thought. In this supreme stillness, the light of Pure Consciousness shines forth.
At this pinnacle of spiritual evolution, the yogi unites with Brahman — the Ultimate Reality. The mystery of existence is unveiled, and all illusions of separation vanish. Enlightened with divine knowledge, the yogi becomes free from the cycle of birth and death, and abides in the eternal realm of bliss and freedom.
This union with the Supreme is the ultimate goal and culmination of all yogic practices—the true epitome of yog.
Wrapping Up : The Path of Ashtang Yog
Ashtang Yog, the Eightfold Path of Yog, is a comprehensive journey of self-purification and inner realization. It begins with the ethical disciplines of Yam and Niyam, progresses through the physical and energetic mastery of Asan and Pranayam, and turns inward with the mental withdrawal of Pratyahar. From there, the aspirant cultivates focused concentration in Dharana, deepens it into unbroken meditation in Dhyan, and ultimately transcends the limitations of body and mind in Samadhi, the state of union with the Supreme Consciousness.
Each limb of Ashtang Yog prepares the seeker for the next, leading step-by-step from outer discipline to inner liberation. It is not merely a set of techniques, but a way of life that harmonizes the physical, mental, and spiritual dimensions of the human being. The culmination of this path is the realization of the Self’s true nature—eternal, blissful, and one with the infinite Brahman.
Ashtang Yog is both a map and a method—a timeless guide for anyone seeking inner peace, self-mastery, and spiritual freedom.
