That’s a wise stance to take and great to warn people about it.
The Islamic folk around my parts buy goats from my friend and sacrifice them on an alter. It is apparently for Allah. But, let’s be real, the Source isn’t receiving those sacrifices or spilled blood. There’s an egregore about that they aren’t fully aware of. Yet, they do the sacrifices and have the feasts anyway.
I’ve attended these before and I give my verbal utterances in the veil of “Allah”. But, the intention within my mind is directed elsewhere and the energy I’m spending isn’t directed to their supposedly omniscient Allah. If Old Boy was up there and watching me profane their rituals like that, I’d have received some scorn by now.
Again though, very good on you for erring on the side of caution and warning. That makes total sense and is necessary. Internal personal work absolutely works, as you finished the comment with. It’s essentially what I’m doing when I attend these Islamic goat sacrifice ceremonies. I’m definitely not telling them all that I’m diverting the power towards my own goals, even though I 100% am doing that internally.
