1.) Can one be a Swaminarayan Hindu without believing Swaminarayan is God/an avatar? More akin to a saint or prophet? Or is it like most denominations of Christianity where if you don't believe Jesus is divine, then you aren't a "real Christian"?

2.) Is this a controversial school? It doesn't seem to have a lot of support outside of the practitioners themselves.

3.) Even though the school is, technically, Vaishnavite, and has a preference for Vishnu and Krishna, where do other Gods stand? Gods such as Shiva, Ganesha, the Goddess, etc.?
