How far exactly can you go as a single practitioner? Once you actually start working with true meditation and the deeper states of Samadhi on a regular basis which seems to start building light within the astral body at least this is what I have seen in the astral in my own experience. So how much of the superior bodies can you start to build as you work profoundly with Samadhi to eliminate the ego? I understand that without the practice of alchemy with a partner you cannot officially raise the serpent of each corresponding body. But the light built from meditation itself seems to be going somewhere. Does it all just accumulate in the solar astral body? Also if one has already built solar bodies in the past how would this start to reactivate their bodies in some way?
