Interesting article. But why put limits on the most advanced things we know and experience: our very being. What I find amazing is many stories of individuals who may have stopped eating and drinking, can survive extreme cold or heat and many other seemingly superhuman abilities. The Buddhist practice of Tummo where one can generate great heat. Stories of the so called 'Buddha Boy' who does not eat, drink, sleep and mediates inside of fires. The famous stories of Mahavatar Babiji who can change his form at will, teleport, read minds, etc etc. I think that if one realizes totally that the body is just light then that is what you get, a light body, capable to anything.
