Reflections on self-realization, Ishraq or Kensho experiences

A while ago while I was in public place, after long meditation, I entered a state analogous to that one experiences between sleep and wakefulness. A women was standing in front of me, saying I need part of the cake.

At this time, I saw something around her waist which was somewhat shapeless, but the closest shape was a circle.

Something told me this was her essence, the one that survives when she passes away.

I saw similar phenomena in my dreams, and it occurred to me this is so or so person. It had a sort of good quality feel: this is a good person.

From scientific point of view, it appears to me, this is the energy of the individual or rather the essential energy of the individual, the one that cannot be created nor destroyed, but changes forms, now this now that and so on.
