Enquiry is the means of knowledge and it consists in hearing the Truth, reflection and meditation; only the state of blissful Peace of awareness in which Brahman alone exists and nothing else, is the true "nature" of Knowledge; the non-revival of the knot of the ego parading as "I" which has been lost once for all, is its "effect"; always to remain fixed as "I am the Supreme Self" just as strongly, unequivocally and unerringly as the heretofore ignorant identification "I am the body" is its end; liberation is its fruit.
