I have come to sense over time that spiritual energy radiates from us in the ever on-going process of death. I first noticed this when my dog was dying. I could see her energies leaving her body, flowing out into the aether. I tried to force these energies back into her body, but obviously, I failed. It was beyond me, but the last time I meditated I focused on containing all of my own energy within me, letting none escape. I could feel myself quickly accumulating energy and my body got ever warmer. I even went outside into the cold(probably about 20 degrees out at the time), but even though I could feel the cold around me, it didn't affect me physically. I could hold this power only for a limited time. Eventually the energy levels were too high to keep bound, either that or I just lost interest, which I do at times.

My initial theory on this is that this process is how people attain certain Siddhis. If one could master this process, I would assume that they could keep alive for as long as they are capable of holding their spiritual energy, as well as being immune to severe cold. I'm not sure about heat. I'll have to test that one to be sure.

And, of course, I would much enjoy the comments and queries of the other members here.
