The only true and firm doctrine

Having studied all the shastras and having pondered over them well, again and again, this Yoga Shastra has been found to be the only true and firm doctrine.

Since by Yoga all this verily is known as a certainty, all exertion should be made to acquire it. What is the necessity then of any other doctrines?

This Yoga Shastra, now being declared by us, is a very secret doctrine, only to be revealed to a high-souled pious devotee throughout the three worlds.
