When encountering evil in the astral plane, I always summon this:

you mean that you call the Tetragrammaton, the God? I say the belilin if I cannot see where he/she/they are, and point them with the first three fingers saying the conj. of Jupiter

Klim Krishnaya Govindaya Gopijana Vallabhaya Swaha!

thank you very much, I will use it, because I encounter evil some times while I dream during the sleep(I steel cannot astral project consciously). When they attack me in the astral, I use the conjuration of Jupiter, but some times if they are many(rare), the bellilin, but this mantra will protect me better. Why do you think I saw the cross in the sky, after thinking about the annihilation of the evil in the world? But now I see I can destroy only the evil in my heart.

If you are eating, eat; if you are getting dressed, get dressed, and if you are walking on the street, walk, walk, walk, but do not think about anything else. Do only what you are doing. Do not run away from the facts; do not fill them with so many meanings, symbols, sermons and warnings. Live them without allegories. Live them with a receptive mind from moment to moment. -Samael Aun Weor, The Revolution of the Dialectic

yes, but I don't believe in coincidences, do you?
