This terse definition hinges on the meaning of three Sanskrit terms. I. K. Taimni translates it as "Yoga is the inhibition (nirodhaḥ) of the modifications (vṛtti) of the mind ".The use of the word nirodhaḥ in the opening definition of yoga is an example of the important role that Buddhist technical terminology and concepts play in the Yoga Sutra; this role suggests that Patanjali was aware of Buddhist ideas and wove them into his system. Swami Vivekananda translates the sutra as "Yoga is restraining the mind-stuff from taking various forms Vrittis.

Patanjali's writing also became the basis for a system referred to as "Ashtanga Yoga" Eight-Limbed Yoga. This eight-limbed concept derived from the 29th Sutra of the 2nd book, and is a core characteristic of practically every Raja yoga variation taught today. The Eight Limbs are:
1. Yama The five "abstentions"): non-violence, non-lying, non-covetousness, non-sensuality, and non-possessiveness.
2. Niyama The five "observances"): purity, contentment, austerity, study, and surrender to god.
3. Asana: Literally means "seat", and in Patanjali's Sutras refers to the seated position used for meditation.
4. Pranayama ("Suspending Breath Prāna, breath, "āyāma", to restrain or stop. Also interpreted as control of the life force.
5. Pratyahara ("Abstraction"): Withdrawal of the sense organs from external objects.
6. Dharana "Concentration"): Fixing the attention on a single object.
7. Dhyana Meditation"): Intense contemplation of the nature of the object of meditation.
8. Samādhi Liberation"): merging consciousness with the object of meditation.
In the view of this school, the highest attainment does not reveal the experienced diversity of the world to be illusion. The everyday world is real. Furthermore, the highest attainment is the event of one of many individual selves discovering itself; there is no single universal self shared by all persons.
