Self-knowledge and its applicability to leading a happy life is my passion. Everything I do seems to lead me back to this. 'Know Thy Self.'
The bug bit me way back in the late 1960s when, as a very non-religious, athiestic-type of person, a book about Theosophy came my way. This got me into reading New Age stuff (hard to come by in the 1960s and 1970s) then into serious meditation.
The more I learn about 'what' and 'who' we are, the more I feel an almost obsessive urge to let others into that knowing.
