This is a short but very good video by the amazing Rupert Spira about the three stages of insight into oneness. It made me aware of ‘where I am’ , which is very useful. (I think I’m in stage 2\3 during some meditations, and during the day in stage 1/2 depending on my activity.) I can sense the truth of stage 3 during the day if I concentrate, but identification stays with the ego. Good stuff.
