Despite its influence on me, I cannot be a Buddhist because I start from Heathenry as my ground of operation. Working from a heathen ontology, you can take refuge, you can engage in the practices, but you will never really be considered a Buddhist by any conventional Buddhists.
I do however think that structures like 'Dzogchen' and non-monastic tantric practices can be used by Heathens (who want to) to engage in a kind of Buddhism without betraying heathen principles.
You just have to ask yourself if bloody sacrifice and in-group based morality will conflict with the goal of your practice.
Germanic paganism is ontologically relational, i.e., animistic. It has its ways of doing things and logic systems that I agree with (naturally however, certain conclusions differ to those of historical heathens as a result of technological and social change). However interwoven with that, I do engage in some kind of a low level of Buddhism that helps frame things in a wider metaphysical perspective. - I respect the precepts and seek to uphold them to a certain extent for my own benefit as well as the benefit of others, the vows similarly.
Yet I would never stand against bloody sacrifice or violence in general, and I may even suggest and be open to the notion that these practices can lead people toward various forms of enlightened states. One cannot help but notice similarities between the state of being an Elf and the luminous body for e.g..
The end goal of Buddhist practice is a realization, a state of being. Even in the times of Shakyamuni's mortal wanderings it was made abundantly clear that there is not just one path toward this realization to attain total freedom and bliss.
I got into paganism via genealogical studies and a genuine pre-existing belief in an other than human world.
I just figured that the system my ancestors used for the longest was the best way of engaging with the other than human world. Since they couldn't even make up their mind about what kind of Christian they were, Episcopalian, Presbyterian, Catholic, I figured that path wasn't the best. It wasn't coherent, it was foreign, and didn't feel real.
Paganism felt like the natural position to take.
From there I've engaged in philosophies that are foreign, but without budging on heathen principles. Buddhism has been my biggest influence, but I am not a Buddhist in any conventional sense at least.
