Fear of Abrahamic and abrahamic satanic imagery

Hi! I am very interested in Kriya yoga, however I grew up in a christian family and still feel unsettled by the idea of "satanic imagery" "magic" "possesion" "demons" or non Christian canonical usage of christian imagery (such as jesus). It seems like Kriya yoga uses alot of Christian imagery and even symbolism that a christian may associate with magic, satanism, etc. This concerns me, as it feels like it would be indicative of a scam, or even worse, something spiritually toxic, putting me at risk of possesion, etc.

I was hoping someone more exposed to kriya yoga could explain to me why their is such prolific imagery of jesus, and other occult associated symbolism. I would also like to know if anyone knew of other yogic practices in the west with the aim of samadhi that are also relatively palatable to western audiences while being safe like kriya yoga (unlike kundalini yoga from what I've heard).

Thank you :)
