1- I read angel enn a long, long time ago and I felt a sense of love, why? And I didn't get this feeling of love from the gods..
I think it's because Angels and other Christian thought forms leverage love to make you vulnerable, open, and manipulable. Trying to get into humans through feelings is much easier than through pure critical reason.
The Christian crap is nothing worth taking seriously since it's all anti-historical, anti-scientific, stolen from older pagan texts, anti-ethical, and anti-logic of simple cause and effect.
The only way you'll believe this crap is to push your feelings. Angels do this, HPS Maxine Dietrich has written extensively about Angels using a false sense of unconditional love or universal love or other kinds of meaningless loves to sneak in. This is nothing new.
The Gods do much better than this angelic buffoonery. When I played the ouija board with Anubis, Anubis would just let me love him. He didn't need any false sense of "Christian love" to create a relationship with me, he was sweet, kind and helpful and it was natural to love him. This is true love not suggestion.
2- Why do I yawn and feel sleepy when I do god rituals?
Probably because by hanging around with angelic stuff like Enn chants or Christian stuff in general you are somehow tending towards that stuff as if it has created a bond with you. I'm hypothesizing, I'm not a "doctor of the soul", but I wouldn't focus on angelic stuff, also because it's obvious that if the soul is pointing in one direction, the other will be somewhere else and no matter how far away it can be observed, you can't take two paths at the same time.
