Jñānāgni

Whether one is a knower of truth or ignorant of it, powers like flying in the air accrue to one who engages himself in some practices . But the sage of self-knowledge has no desire to acquire these. These practices bestow their fruit on anyone, for such is their nature. Poison kills all, wine intoxicates all, even so these practices bring about the ability to fly, etc., but they who have attained the supreme self knowledge are not intenrested in these, O Rāma. They are gained only by those who are full of desires; but the sage is free from the least desire for anything. Self knowledge is the greatest gain; how does the sage of self-knowledge entertain any desire for anything else?
