On the necessary training required(?)

[WaitingVainly]

Um hi I am currently training myself to be psychically receptive to the angels found in Trithemiu's Art of Drawing Spirits into Crystals, I've my table of practice, my wand and a black mirror.

Er so far I've done some conjuration, just once but I've yet to receive a two-way communication with the angels. I might be psychically dud so I did some pore breathing exercises and deep meditation to still my thoughts and to increase receptivity. Is there anything I am missing folks?

Or am I just impatient?
Suggestions, opinions and advice are appreciated
