I did my first course in 2000 and I must admit I'm not very regular and I wish I could be a lot more but whatever I do and whenever I do it it just is just something you can experience. It's kind of removing all the layers from your you know body mind spirit whatever and just making it purer and purer andpurer so you can literally examine where is this memory from where is this aspiration fromwhere is this thought kind of originating? And if you can keep kind of removing that as they very well said in the Upanishad above the senses the five senses above that is the mind above the mind is the ego, which is really your unmanifested cause
