Also, is salvation even an Indian a Hindu concept anyway?

Salvation from what, is the real question. The fact that it goes unstated kind of implies the Christian cultural baggage comes with it, which would then imply "hell to the fuck no".

Regardless, though, I'm pretty sure it's going along with your dharma that gets you good consequences, not the fact that your childe is banging a god. Hindu gods (again, IIRC) are part of the cycle, not above it.
