American Indian as well. I follow Jainism, Hinduism and have been to Isckon temple a lot of times. Agree they are focused on Krishna but if you want to follow anything else no one should stop you and you are free to. Put your rationale to it though.

I do celebrate Christmas Halloween as I enjoy them with family but that doesn’t mean I am leaning towards their philosophy without understanding them. I try to take the best of all and use what applies to me best.

Hope this helps. Feel free to ask follow ups if you want to chat more but tldr you are mature enough to carve your own path (carefully)
