That's what I worry about. I feel sort of guilty incorporating Buddhism in to my spiritual practice when I have the feeling that most Buddhists would not approve that I am not 100% Buddhist. I could be wrong... BUT, it feels right to me to believe in both, despite the conflicts, and I guess that's what it has to come down to in a spiritual practice. Sometimes you have to make your own way. I am still relatively new to Buddhism, but I have not read anything to indicate that Buddha approved of blindly following the rules, just for the sake of it. Seems pretty contradictory to the original teachings, as I understand them.
Hi. Would like to respond to bold faced section specifically, with a direct quote from the Buddha himself that confirms the opposite of blind faith. It's from the Kalama Sutta in the original Pali (language) Canon. I copied this from oaks.nvg.org/kalama.html that has 4 free translations of the scripture quoted below. The words in parentheses are for inserted by the translators for clarification:
"Do not go by reports (repeated hearing), by legends, by traditions, by rumours, by scriptures, by surmise, conjecture and axioms, by inference and analogies, by agreement through pondering views, by specious reasoning or bias toward a notion because it has been pondered over, by another's seeming ability, or by the thought, 'This monk (contemplative) is our teacher."
However, Kalamas, when you yourselves know: "Such and such things are unskilful (bad); blameworthy; criticized by the wise; and if adopted and carried out lead to harm and ill and suffering," you need to abandon them... On the other hand, when you know for yourselves that, "These and these things are skillful; blameless; even praised by the wise; and lead to welfare and happiness when taken up and carried out, then you should enter and remain in them."
If this helps you in your search for resolution to be a Pagan-Buddhist or just "Buddhist," I don't know, but I hope it does in some way. Historically speaking, actually, in India at the Time of the Buddha specifically, there was a huge amount of philosophical and religious discourse and meeting of traditions, and it appears that there was blending of rituals and traditions. For example, I have heard from reliable sources, though I haven't done the research myself, that Hindu and Buddhist Tantra (and I'm not talking about the Western confusion "Tantra" and the Kama Sutra, etc. BTW!) share many similarities, such that there is debate on which tradition was the bigger influence on the other.
Also, it might help to know that in the Tibetan Vajrayana and Bon traditions, especially, there is a major emphasis on understanding how the 5 physical elements and their relation with the human inner (spiritual elements) function and can be manipulated to attain Enlightenment or benefit others. In this regard the Buddhist "ngakpa" and Bon "shaman" (a word I hesitate to use, again for its modern over-use in the West), is very similar to a sorcerer or, perhaps, a Pagan or Wiccan/Witch. I know almost nothing about Pagan traditions though, so don't fault me for my ignorance. you might find further reconciliation there, you might find everything you need in some traditions of Buddhism you might not have explored yet, or you might find there is no contradiction between taking Buddhist precepts or becoming Buddhist "officially" and maintaining ties to the Pagan community, too. There are MANY Buddhist traditions, lineages and sub-lineages and kinds of teachers and sanghas/communities. Explore until you find the one(s) that are most welcoming and understanding to needs and connections.
The only thing I would say that might make the two mutually exclusive is if there are fundamental Buddhist precepts that would be broken by certain necessary activities in the Pagan tradition, or vice versa. Philosophical contradictions are maybe not so crucial, because even within Buddhism, there are many philosophical schools that have argued for centuries! =)
Warm Regards to all conflicted Pagan Buddhists (or for that matter, Jewish-Buddhists, or Christian-Buddhists or any others!")
