Yoga Sutras of Patanjali
Patanjali divided his Yoga Sutras into 4 chapters or books (Sanskrit pada), containing in all 196 aphorisms, divided as follows:
Samadhi Pada (51 sutras) - Samadhi refers to a blissful state where the yogi is absorbed into the One. The author describes yoga and then the nature and the means to attaining samādhi. This chapter contains the famous definitional verse: "Yogaś citta-vritti-nirodhaḥ" ("Yoga is the restraint of mental modifications").
Sadhana Pada (55 sutras) - Sadhana is the Sanskrit word for "practice" or "discipline". Here the author outlines two forms of Yoga: Kriya Yoga (Action Yoga) and Ashtanga Yoga (Eightfold or Eightlimbed Yoga). Kriya yoga, sometimes called Karma Yoga, is also expounded in Chapter 3 of the Bhagavad Gita, where Arjuna is encouraged by Krishna to act without attachment to the results or fruit of action and activity. It is the yoga of selfless action and service. Ashtanga Yoga describes the eight limbs that together constitute Raja Yoga.
Vibhuti Pada (56 sutras) - Vibhuti is the Sanskrit word for "power" or "manifestation". 'Supra-normal powers' (Sanskrit: siddhi) are acquired by the practice of yoga. The temptation of these powers should be avoided and the attention should be fixed only on liberation.
Kaivalya Pada (34 sutras) - Kaivalya literally means "isolation", but as used in the Sutras stands for emancipation, liberation and used interchangeably with moksha (liberation), which is the goal of Yoga. The Kaivalya Pada describes the nature of liberation and the reality of the transcendental self.
The eight limbs (asthanga) of Raja Yoga
The eight "limbs" or steps prescribed in the second pada of the Yoga Sutras are: Yama, Niyama, Asana, Pranayama, Pratyahara, Dharana, Dhyana and Samadhi.
Ashtanga yoga consists of the following steps: The first five are called external aids to Yoga (bahiranga sadhana)
- Yama refers to the five abstentions. These are the same as the five vows of Jainism.
-
- Ahimsa: non-violence, inflicting no injury or harm to others or even to one's ownself, it goes as far as nonviolence in thought, word and deed.
- Satya: truth in word & thought.
- Asteya: non-covetousness, to the extent that one should not even desire something that is not his own.
- Brahmacharya: abstain from sexual intercourse; celibacy in case of unmarried people and monogamy in case of married people. Even this to the extent that one should not possess any unholy thoughts towards any other man or woman except one's own spouse. It's common to associate Brahmacharya with celibacy.
- Aparigraha: non-possessiveness
- Niyama refers to the five observances
-
- Shaucha: cleanliness of body & mind.
- Santosha: satisfaction; satisfied with what one has..
- Tapas: austerity and associated observances for body discipline & thereby mental control.
- Svadhyaya: study of the Vedic scriptures to know about God and the soul, which leads to introspection on a greater awakening to the soul and God within,
- Ishvarapranidhana: surrender to (or worship of) God.
- Asana: Discipline of the body: rules and postures to keep it disease-free and for preserving vital energy. Correct postures are a physical aid to meditation, for they control the limbs and nervous system and prevent them from producing disturbances.
- Pranayama: control of breath. Beneficial to health, steadies the body and is highly conducive to the concentration of the mind.
- Pratyahara: withdrawal of senses from their external objects.
The last three levels are called internal aids to Yoga (antaranga sadhana)
- Dharana: concentration of the citta upon a physical object, such as a flame of a lamp, the mid point of the eyebrows, or the image of a deity.
- Dhyana: steadfast meditation. Undisturbed flow of thought around the object of meditation (pratyayaikatanata). The act of meditation and the object of meditation remain distinct and separate.
- Samadhi: oneness with the object of meditation. There is no distinction between act of meditation and the object of meditation. Samadhi is of two kinds:
