Dive Bomb, my current understanding of different "channels" comes from this link:
Treatise on Astral Projection - Part 2 - Robert Bruce
Its says the commonly accepted names for the seven known levels of existence, from lowest to highest, are: Physical, Astral, Mental, Buddhic, Atmic, Anupadaka and Adi.
You travel within each level and from one to the next by raising your vibration. It is my understanding that Evil can only vibrate at the Physical, Astral, and Mental frequencies.
You can easily reach the Mental dimension by taking LSD or shrooms or any psychedelic drug. You will have a “bad trip” if you project fear rather than love when you trip.
Hopefully Erin can clarify that for us. Please don’t take my word as the truth and take LSD to have an enlightening experience.
