self knowing is not a method. It is constant watchfulness of ego activity. In the intensity of watchfulness we come to know the falsity of contents of mind and so in the intensity of watchfulness the contents evaporate. Then the mind is empty. This watchfulness is not against the mind but with watchfulness ego activity comes to a stand still and so we go beyond the ego and we penetrate the unknowable. We cannot penetrate the unknowable with the known. All methods belong to known and you cannot jump into unknown by clinging to known. A mind that is empty of known has the capacity to jump into the unknowable. Mind with contents is conditioned and so always in conflict. Unless we see the falsity of conditioning mind is in conflict and split. Split mind is a fragmentary mind and is never free of ego activity like greed, anger, sex etc. Such fragmentary mind can never comprehend the truth. Mind without any contents can comprehend the truth. When there is freedom from background of conditioning there is intensification of life. Life is a process of challenge and response and we respond adequately to challenge only when we are free of conditioning. Till then action is incomplete and there is perennial conflict. That is why JK insisted on emptying of contents of the mind.
