Ashtanga Yoga
Yoga philosophy is one of the most profound branches of Indian philosophy, and its chief aim is to purify the mind and lead the human being toward liberation. According to the Yoga tradition, suffering, restlessness, ignorance, and attachment arise mainly because of the fluctuations of the mind. Yoga is the discipline by which these fluctuations are restrained and the mind becomes focused, pure, and steady. Thus, yoga is not merely physical exercise; it is a complete method for disciplining the body, mind, senses, intellect, and self. In his Yoga Sutras, Patanjali divided this discipline into eight limbs. This is known as Ashtanga Yoga.
Patanjali says:
“Yama-niyama-asana-pranayama-pratyahara-dharana-dhyana-samadhi-yo’stangani”
That means Yama, Niyama, Asana, Pranayama, Pratyahara, Dharana, Dhyana, and Samadhi are the eight limbs of yoga.
Through these eight limbs, the practitioner gradually moves from the outer world to the inner world and ultimately becomes capable of realizing the true self. The first five limbs of Ashtanga Yoga are called external discipline, and the last three are called internal discipline. External discipline prepares the body and senses, while internal discipline leads the mind toward deep meditation and samadhi.
The Aim of Yoga
The main aim of yoga is the cessation of mental fluctuations and the realization of the true nature of Purusha. According to Samkhya-Yoga philosophy, Purusha is pure consciousness, but because of its association with Prakriti, it identifies itself with the body, mind, intellect, and ego. This mistaken identification is the root cause of suffering. Through Ashtanga Yoga, this ignorance is removed and discriminative knowledge between Purusha and Prakriti is attained. This discriminative knowledge is the first and most important step toward liberation.
Therefore, the aim of yoga is not only bodily purification but also self-purification, mental purification, and the attainment of wisdom. For this reason, yoga is regarded as a deep philosophical and spiritual discipline.
Yama
The first limb of Ashtanga Yoga is Yama. Yama is a form of moral restraint that purifies the practitioner’s social conduct. Patanjali says:
“Ahimsa-satya-asteya-brahmacharya-aparigraha yamaah”
That is, Ahimsa, Satya, Asteya, Brahmacharya, and Aparigraha are the five Yamas.
Ahimsa
Ahimsa means not causing harm to anyone through body, speech, or mind. It does not refer only to external violence; even wishing harm to others in the mind is included within violence. In yogic practice, Ahimsa is extremely important because violence creates impurity and unrest in the mind. Ahimsa does not mean weakness; rather, it means compassionate concern for the welfare of all beings. This principle develops kindness, tolerance, and empathy in the practitioner.
Satya
Satya means consistency in thought, word, and action. To say what one knows, sees, and considers right is truth. However, in Yoga philosophy, truth is not merely factual accuracy; it must also be beneficial. A truth that harms others is not acceptable for a seeker. The practice of Satya makes a person fearless, pure, and trustworthy.
Asteya
Asteya means not stealing. It includes not coveting another person’s property, rights, or dignity. Not only material theft but also taking someone else’s time, ideas, or credit is ethically considered theft. Practice of Asteya reduces greed, calms the mind, and increases self-control.
Brahmacharya
Brahmacharya means restraint of the senses. In particular, it means controlling desire and directing energy toward higher spiritual practice. It is not only sexual restraint; it is a disciplined life in which all senses are controlled. Brahmacharya increases strength, steadiness, willpower, and concentration in the practitioner.
Aparigraha
Aparigraha means not accumulating more than what is necessary and giving up the greed for enjoyment. Attachment to excessive possessions, objects, or comforts makes a person restless. Through Aparigraha, greed decreases, a spirit of detachment arises, and the mind becomes simple. It is highly useful for yogic practice.
Niyama
The second limb is Niyama. Niyama refers to positive disciplines of self-restraint. Patanjali says:
“Shaucha-santosha-tapah-svadhyaya-ishvara-pranidhanani niyamah”
That is, Shaucha, Santosha, Tapas, Svadhyaya, and Ishvara Pranidhana are the five Niyamas.
Shaucha
Shaucha means purity. It is of two types: external and internal. External purity means cleanliness of the body, clothes, and surroundings, while internal purity means removing hatred, ego, jealousy, anger, and malice from the mind. Practice of Shaucha makes the mind clear and calm.
Santosha
Santosha means being content with what one has received. Excessive desire makes a person unhappy. Santosha reduces greed, brings peace to the mind, and stops unnecessary restlessness. It is a very important mental state in yogic practice.
Tapas
Tapas means endurance and disciplined practice. It refers to the austerity by which the demands of the body and senses are restrained. Fasting, controlled eating, fixed routine, and patient practice are included in Tapas. Tapas makes the practitioner firm, determined, and steady.
Svadhyaya
Svadhyaya means self-study and study of sacred texts. Reading the scriptures, Yoga texts, Upanishads, and chanting mantras are included in Svadhyaya. Through this, the desire for self-knowledge awakens. Svadhyaya enlightens a person from within.
Ishvara Pranidhana
Ishvara Pranidhana means complete surrender to God. When the practitioner offers all actions, results, and ego to the Supreme, the mind becomes purified easily. Ishvara Pranidhana frees yogic practice from selfishness and ego-centeredness.
Asana
The third limb is Asana. Patanjali says:
“Sthira-sukham asanam”
That is, the posture in which the body remains steady and comfortable is called Asana. The aim of Asana is not simply a sitting position, but a bodily state in which one can meditate for a long time.
Yoga texts mention many asanas such as Padmasana, Bhadrasana, Swastikasana, Vajrasana, and Dandasana. Practice of Asana makes the body healthy, flexible, and free from disease. At the same time, mental restlessness is reduced. Asana prepares the practitioner for meditation, because if the body is not steady, the mind also cannot become steady.
Pranayama
The fourth limb is Pranayama. Pranayama is the regulated control of breath. Patanjali says:
“Tasmin sati shvasa-prashvasayor gati-vicchedah pranayamah”
That is, when Asana is mastered, the regulation of the movement of inhalation and exhalation is Pranayama.
Pranayama has three main forms:
-
Puraka: inhalation.
-
Rechaka: exhalation.
-
Kumbhaka: retention of breath.
Pranayama regulates the vital energy of the body. There is a deep relationship between breath and mind; when breath is restless, the mind becomes restless, and when breath is controlled, the mind becomes calm. For this reason, Pranayama is regarded as a very important preparation for meditation.
Pratyahara
The fifth limb is Pratyahara. The senses naturally rush toward external objects. Bringing those senses back from external objects and turning them inward is Pratyahara. Patanjali says:
“Swavisaya-asamprayoge cittasya svarupanukara ivendriyanam pratyaharah”
That is, when the senses are disconnected from their objects and follow the nature of the mind, it is called Pratyahara.
Pratyahara is very necessary because without control of the senses, higher yogic practice is impossible. If the eyes, ears, tongue, nose, and skin keep moving toward external objects, the mind can never become steady. Therefore, Pratyahara is the practice of withdrawing the mind from the attractions of the outer world.
Dharana
The sixth limb is Dharana. Fixing the mind steadily on a particular object, place, or thought is called Dharana. Patanjali says:
“Desha-bandhash cittasya dharana”
That is, binding the mind to a particular place or point is Dharana.
During Dharana, the mind does not scatter; it remains centered on one object. The midpoint of the eyebrows, the tip of the nose, the heart-lotus, or a sacred deity may serve as the object of concentration. Dharana is the initial stage of meditation. Here the mind consciously holds the object.
Dhyana
The seventh limb is Dhyana. When Dharana becomes continuous and unbroken, it is called Dhyana. Patanjali says:
“Tatra pratyaya-eka-tanata dhyanam”
That is, the continuous flow of cognition within that concentration is Dhyana.
In Dhyana, the mind becomes so deeply absorbed in one object that no other thought can enter. Dharana has fragmentary attention, but Dhyana has uninterrupted flow. Dhyana makes the practitioner inwardly focused, calm, and concentrated. At this stage, knowledge becomes subtler, deeper, and more stable.
Samadhi
The highest limb of Ashtanga Yoga is Samadhi. When meditation becomes so deep that the distinction between the meditator, meditation, and the object of meditation disappears, Samadhi is attained. Patanjali says:
“Tadevartha-matra-nirbhasam svarupa-shunyam iva samadhih”
That is, when only the object of meditation shines forth and one’s own self appears almost absent, that state is called Samadhi.
Samadhi is the highest form of concentration of the mind. In this state, the practitioner experiences reality in a transformed way. Through Samadhi, realization of the true self occurs, and discriminative knowledge between Purusha and Prakriti becomes clear. This is the ultimate goal of Yoga philosophy.
External and Internal Discipline
The first five limbs of Ashtanga Yoga—Yama, Niyama, Asana, Pranayama, and Pratyahara—are considered external discipline. They prepare the body, senses, and moral life. On the other hand, Dharana, Dhyana, and Samadhi are internal discipline. They are directly related to the subtle levels of the mind.
These two kinds of discipline complement each other. Without external discipline, internal discipline cannot become firm, and without internal discipline, external discipline cannot bear full fruit. Therefore, Ashtanga Yoga is a step-by-step and complete system of spiritual progress.
Conclusion
Ashtanga Yoga is a complete path of human discipline. Through it, a person can purify and regulate the body, mind, senses, and self. Yama and Niyama establish moral discipline; Asana and Pranayama keep the body healthy and steady; Pratyahara turns the senses away from external objects; and Dharana, Dhyana, and Samadhi lead the practitioner into the deeper levels of inner consciousness. These eight limbs are mutually supportive and gradually guide the seeker toward a higher spiritual state. Therefore, Ashtanga Yoga is not merely a physical practice but a unique philosophical path of self-purification, mental discipline, and liberation. In the present age of restlessness and excessive materialism, this yogic discipline can lead human beings toward peace, self-control, concentration, and self-realization.
