Hello gnostic instructors, I am wondering on initiated opinions of Crowley's techniques given for controlling the mind, mainly, ceremonial magick. Vibrating divine names, invoking, banishing, working with the elements, inflaming pentagrams and hexagrams with the imagination.. Are these useful techniques for learning to control the mind, and using the will to have dominion over nature? Is it a path worthy of pursuing, or having some knowledge in, to work towards awakening the consciousness? I ask because I have been doing some rituals (mainly the lesser invoking/banishing ritual of the pentagram) and there are interesting results which insue from it. However, I am wondering if there is anything negative about it or any reason it should be avoided. Also, when he teaches pranayama, he does it in a way which works towards simply regularizing the flow of energy in the body - simply breathing in through one nostril for 10 seconds, holding for 40, breathing out the opposite for 20. Is this type of pranayama negative in any way? Thank you in advance.
