Lord Kapila, the Personality of Godhead, who is the highest authority on yoga, here explains the yoga system known as ashtanga-yoga, which comprises eight different practices, namely yama, niyama, asana, pranayama, pratyahara, dharana, dhyana and samadhi. By all these stages of practice one must realize Lord Vishnu, who is the target of all yoga. There are so-called yoga practices in which one concentrates the mind on voidness or on the impersonal, but this is not approved by the authorized yoga system as explained by Kapiladeva. Even Patanjali explains that the target of all yoga is Vishnu. Ashtanga-yoga is therefore part of Vaishnava practice because its ultimate goal is realization of Vishnu.

Where did that come from?
