I think of ascension and self-deification to be one and the same. Some achieve this through kundalini awakening, some through other methods. There could be priests, yogis, shaman, psychedelic drug enthusiasts, etc. etc., everywhere and anywhere in the world, from the far past right up until this very second, who have achieved ‘ascension’, all using different methods. I suppose you can think of it as the peak of the mountain, and most people on a spiritual journey up the mountain eventually see through the clouds and come to this realisation. No matter which path they take to climb the mountain.
This is pretty much it. Everyone will explain it differently, or what it means to them… to me, it is simply realising that you are god. You won’t vanish into a puff of smoke, or become a soulless sexless shell with no earthly desires. You will maintain your ego, as in, your sense of self – ideally. The idea is not to renounce the material world entirely.
