When newcomers approach Hinduism, sometimes they think it's just so complicated. Some Hindu scholars see it that way to, and write long books full of explanations. Yes we have several major schools, various sects, and 30 or so native languages.
Other faiths are complicated too when you approach it from the idea of trying to understand it all.
Imagine trying to understand a car, and how it operates by looking at the entire package all at once.
For the average Hindu bhaktar, life is pretty simple. Why? Well, mostly because we've managed to narrow it down. We have realised we don't need to understand it all at once. I'm reminded of an old priest friend of mine, when he gave advice. A devotee would be having some kind of problem, and go and ask for some advice. The priest would say, "Go Pray Ganesha." That was it. Ridiculously simple.
My own Guru,when asked to say a few words to another Guru's congregation, would say, "Obey your Guru." ... or some simple thing.
What does knowing all this stuff do? Do we even remember it, let alone apply it?
