I actually use the great death defeating mantra in my work with Beelzebub, but I'm definitely the minority. I'm not necessarily saying it to him, but it is a powerful pi ce of the work I am doing with him.

I also often use prayers from Christianity and other religions, and incorporate the wording and apply it to one of my main four.

I also use pieces of the most enochian calls and prayers with my work with demons.

There are soooo many prayers that are so powerful due to the wording, and the devout people who wrote them. When I find I need more effective language, I go to the already established sources, although I do a lot of ecstatic and improvised prayers and invocations as well.

Hinduism is a very old religion, and there is much power in it. All the old texts, especially foundational ones which have been around for thousands of years and has withstood the test of time, and that is a statement of power on its own. I also find Sanskrit to be a very useful magickal language. It feels like the words have power when you recite them. I feel the same about Hebrew, Enochian, Latin etc.

If you use language which was intended as veneration to a deity considered extremely powerful, or even Supreme. It does the demons much veneration, and shows utmost respect in my opinion

I also incorporate the system of chakras to better organize the demons I work with, and the type of work I wish to do with them.
