All mental weaknesses come to an end by self-effort based on the wisdom which arises in one who is firmly rooted in self-knowledge.The distress of the mind is got rid of by enquiry into the nature of the self.When you have gained self-knowledge and when your consciousness has infinitely expanded, your mind no longer falls into the cesspool of this world.Not till one renounces everything is self-knowledge gained: when all points of view are abandoned, what remains is the self.This is true even of life in this world: one does not get what one desires unless the obstacle to it is removed.It is even more so in self-knowledge.
