I _accidentally_ fell into a vipassana state of mind after the first time trying a particular religious chant, seriously, from out of the pains of boredom as a 20 year old.
At the time I lived nearby mountains, and after 'coming to', I saw them through the window. I cannot describe to you the overwhelming feeling of beauty and awe that crashed over me. It was as though this was the very first time I had ever seen mountains. I think the best description I can manage comes from 'Both Sides Now' by Joni Mitchell.
'I've looked at clouds from both sides now From up and down, and still somehow It's cloud illusions I recall I really don't know clouds at all'
The experience was so disorienting. As if I was seeing the mountains for what they were directly through my senses and not mediated by my knowledge of what mountains were like, linguistically.
It changed my entire life -- weeks later later I lost my job and fell into a 5 year extreme depression / anxiety spell in the attempt to reconcile my adolescent religious upbringing with the continued insight from that experience. Absolutely worthwhile, in hindsight, but it cost me near everything for it.
