No it is an alkaloid from trees like accasias and some grasses etc.
It liberates the conciousness from the body, and then the awareness from the conciousness. So that the observer becomes the awareness, totaly loosing any sense of self or even of the existance of selves...
Being returned from that state into your daily conciousness is like being shat out into a toilet world. It may be too much for some, it may be too much for me. I no longer have fear, so I will need to find reason, if I were to ever give it up... clawing my way to haveing just a few more seconds of that.
This is a longer term result. In the short term you may see lots of beautiful patterns and maybe some "entities" depending how deep you fall into yourself... But eventualy you will be rather than see. And do rather than think. Our holiest thoughts are just the stopgaps for the emptiness between our righteous deeds.
