As in all cultures, it takes an event or personality behind a philosophy- the release of a book, a political event or some art form to push something to the forefront. Sage Patanjali was this for yoga as a system with the release of the Patajali Yoga Sutras. In context, it is a part of six systems of philosophy in India:
* Yoga - the process of union of individual consciousness with universal consciousness
* Vedanta - knowledge of Self, universe and God.
* Sankhya - philosophical and largely dualistic classification of the universe
* Vaishesika - analysis and characterising of the universe
* Nyaya - logic. Essentially the 'Aristotelian logic of India', it is the fundamental logical basis upon which Indian philosophy has been built
* Purva-Mimamsa - laws of formal religion, sacrifices, etc. The emphasis here is on correct action rather than correct belief.
