DMT and its effects are absolutely amazing. This is one of the rare Data points which can connect so much within our reality, and can reveal a great deal about ourselves, the universe, and our place in it. What I find markedly relevant with the Subject of DMT, is that the people whom ingest it and have powerful spiritual experiences, in nearly ALL these cases meet some spirit guide which reveals the oneness of all things, the universe of total intent, and our choice to be here on earth at this time.
It is as if there is a certain level of clarity of consciousness which we can attain by taking DMT, and having this experience. Others have done it with out the DMT experience, but these accounts confirm a great deal about our reality, and its foundation in Consciousness.
