I like to study; and, have been studying my whole life. So, that's part of my faith. I was reading recently in the book our master gave us when we took the refuges. After taking the refuges, we also vow that we do not respect or practice what is taught by Devas, Spirits, or Demons. We don't respect a practice externalist faiths or heterodox beliefs. We do not respect or associate with evil friends and wicked crowds. It's somewhat of a harsh translation from Vietnamese.
I looked it up already and it said Devas are divine beings, some sites mention them as gods. The Lotus Sutra mentions them as the same level as human beings who come to hear The Dhamma from The Buddha while I haven't yet understood the role of Devas in the Pali suttas yet.
Are you familiar with the refuge in Zen Vietnamese Buddhism about not practicing what is taught by the Devas?
Do Devas teach anything and if they do, what teachings do they give that contradict the Dhamma of The Buddha himself?
I'm not just a meditator but I go all out so this will be and is my life not something I study externally. Do you have some respectful insight on how Devas can hinder our practice in worship and meditation of the Dhamma and our spiritual growth as Buddhists?
