Once into my 40s i am not sure whether its very natural or whether its my apetite - but i seem to have picked up the mystic path... a path of discovery...self discovery...discovery of the chosen ONE.. i am sure this is not renunciation - but its more about knowing what i must do and what i need to do! I get attracted to Sufism, bhakti vedanta, Ramana Maharshi teachings, Sai's life and teachings, etc etc etc....
As a start point here is the first link that i have found very interesting....
