There is alot I don't understand about Deity worship. I remember the nice analogy Srila Prabhupada used about the authorized mail boxes being just as good as the post office. So my first question is: what makes the Deity of Krsna (or His many other forms) "authorized"? Is any picture or statue of Krsna worshipable, just like the Deity? Are the scriptures equally worshipable? Understanding that everything is coming from Krsna and everything is part of Krsna, "vasudevah sarvam iti", isn't everything worshipable? If someone attempts to steal or harm the Deity, should one be prepared to kill or be killed to protect the Deity? It's not that I doubt the authenticity of Deity worship. I just want to broaden my understanding for preaching purposes.
