I wish to inquire the kind of discipline which is necessary to come upon Enlightenment. Or does it require no discipline at all? However it is obvious that a certain discipline is necessary. By simply allowing the mind to go on its own way, it will never arrive at anything worthwhile. Thoughts, being self-repetitive keep on going endlessly, one after the other. By thoughts I mean here, psychological thoughts, arising from ego. Enlightenment is not in the realm of thoughts. It happens with the natural cessation of thoughts. How to come to the end of thoughts? When does the mind end? To understand it, first of all we have to find out the root cause of thoughts. If watch thoughts deeply you will find out they arise from unrest within. Doesn’t it?
