Patanjali Yoga Sutras

Patanjali's yoga is also known as 'Astang yoga' (Astang means eight limbed). In Sadhan Pada, Patanjali narrates eight limbs of yoga practice. Interestingly, only one of them deals with physical postures, and that too, mainly with seating positions. The eight limbs are as follows:

1) Yama (abstentions): Ahimsa (non-injury), Satya (truth), Asteya (non-covetousness), Brahmacharya (continence) and Aparagriha (abstinence from avarice).
