au?thor?i?ta?tive/əˈTH?riˌtātiv/Adjective
- Able to be trusted as being accurate or true; reliable: “clear, authoritative information”.
- (of a text) Considered to be the best of its kind and unlikely to be improved upon.
I first came across the term “authoritative text” when I was beginning to read about Indian philosophy. One or two of the books I was reading cited various texts that were considered authoritative with respect to a particular school of philosophy. I was surprised to find that the only text considered to be authoritative with respect to the yoga darsana is Patanjali’s Yoga Sutras. I assume that the other books mentioned here were not considered authoritative because they aren’t works of philosophy. But I take it that you’re not interested in just philosophy.
Would you consider the Vedas a yogic book?
Only if you are into yoga as a spiritual practice. The Upanishads, which are part of the Vedas, are full of spiritual practices and can be useful, but difficult to understand in a lot of cases.
