Dude!
Ganesh (like all those Hundu dietys) is just another of the many faces of God. Just like Jesus and many others. It's the way they see cosmos. God is everywhere, a concept that I haven't heard in the Christian world since I was in Bible class as a child.
speak for yourself. I totally believe in the idea that God is everywhere. He's everywhere that you can find unadulterated joy: In Ronnie Foster's solo on It's Your Thing, in the roar of an old Vette when you step on the gas, in the sky when you can see stars for miles and miles, in the fields when you see flowers in colors you didn't know existed...
The way that the hindi dieties had been described to me (by a hindi) was much along the same line as the catholic saints: there is one big god that we all know and love, and then you pray to certain deities for certain things. That would make Ganesh his own bad self, among a crowded field of other dieties.
I wouldn't pretend to be an expert on Hinduism, but like any religion, there are often many interpretations.
Good to hear that you see and hear God everywhere, most Christians I know have never mention the bliss of the living moment.
