In this world there is nothing as sublime and pure as transcendental knowledge. Such knowledge is the mature fruit of all mysticism. And one who has achieved this enjoys the self with in himself in due course of time. The sacrifice of knowledge is greater than the sacrifice of material possessions, after all the sacrifice of work culminates in transcendental knowledge.    Therefore one who has renounced the fruits of his action, whose doubts are destroyed by transcendental knowledge, and one is situated firmly in the self, is not bound by works. Therefore the doubts which have arisen in your heart out of ignorance should be slashed by the weapon of knowledge.
