Excuse me for my bad english!
The only thing I can tell is that I didn’t experienced anything.
It was something undescriptible that happened a couple of months ago: I was sitting trying to meditate when… I just stopped trying to control my thoughts… Something went from my belly and rose to the top of my head… it was an explosion of light and I was thtat light and there was nothing else but that light: inside as well as outside, from the region of my heart there was a kind of ray of light that was ‘connected with the universe and at a moment, it was like all the energy that was projected by the “explosion” was coming back to me…but huge!!! My heart was trembling of all this beauty, it was as a dream and I still can’t believe that this happened. No word can really explain what it was, because words are just approximations.
