I think that hinduism has evolved over a long period of time and it has gone through all the rigors of time.This testing of Religion has converted it into a philosphy rather than a religion. This has ensured that the philosphy has perfected itself. Well time will allow only goods things to last. As it is said in Sanskrit "Satyam Shivam Sundaram" What is truth is shiv,what is truth is beautiful,and things which last over a longer period are the ones which are higher truths. So I guess just wait for the truth to be revealed itself.
