Nepe Dai, Darshan! You will get answers of all of your questions, have some patience! However, don't hesitate to raise the questions. I will not address them individually, you have to find them in my postings. However, here is something I must address. It is clear from this that a PERFECT "DISCIPLINE" is not essential for acquiring KNOWLEDGE Depends on how much subtle knowledge you want! More you are disciplined, less disturbances you will find in your mind (more concentration) and your wisdom will be more penetrating. Very straight forward example is: To learn Biology you have to be more disciplined than to learn Farming. Higher degree of discipline cause higher concentration leads to highly penetrating knowledge. To acquire the knowledge of subtal reality you have to have pure discipline; to acquire the knowledge of subtler reality you have to have purer discipline, and to acquire the knowledge of the subtalest reality, you must have ultra pure discipline. I will illustrate this in your language ie the language of science. Wait for it!
