I'm sort of chuckling here because while I don't think a shudra, say, would have an issue with my aspiring to their varna, with many, many of the Brahmins I've encountered, it might, no, it would be another story. I cannot discount the majority of my experiences both here in the West and in India with "native" Brahmins; all things considered, such as my appearance as a white, Western Hindu woman--my aspirations, obvious though unstated, were often met with arrogance, resistance, derision or thinly veiled amusement. And that included not only the social elites who "ran" with my famous guru, but also a chunk of the greedy pujaris, as well. Oh, well, LOL, as you say, "Not my problem." However, I would be remiss in my duty if I didn't note that it's refreshing not to get that vibe from you, Sayakji.
There's a westerner working right alongside the Brahmin priests at Rameswaram. He looked far too busy to be able to share his story though.
