I'm currently reading "The Practical Kabbalah" by Ambelain and translation by Vaughan, to write a post on conjuring the Shem angels.
Preferably without tools, props or candles and incense. If I can do it, anyone could. What I mean is I have no clairvoyance or clairaudience.
On Getting near to God through the nineteen Shem angels Ive posted about, from 72 Angels of Magick, I will try to include Raziel and the mantras used to call down the angels near, and thus these mantras could be verified for safetys sake and if there are any other mantras, say healing, protection, drawing near to God, having the knowledge and wisdom and understanding (supernal triangle) of God, using (Metatron) the Voice of God, etc. If at all possible.
