u fool.. if u have no knowledge of Hinduism, then u must not speak...An idol is a pointer to the Truth. For example, a mother tries to show the moon to her child that she is holding in her arms. She does this by pointing her index finger at the moon and telling the child, "see the moon." Initially the child thinks that the mom's finger IS the moon. As the finger gradually points towards the moon, the child's eyes also move towards the moon, and eventually, the child spots the real moon--at which point the finger is not needed anymore. The finger served as the idol. It was necessary in the beginning, because it helped to point to the Truth. When Truth is discovered, the idol is not needed anymore. That's exactly how Hinduism views idol worship. Seekers who cannot grasp the Oneness and universality of God can worship idols, as idols point to the One Truth.
It seems possibly ironic somehow that you chide us for not knowing Hinduism while at the same time quoting a Buddhist scripture. And if I recall correctly, that particular Buddhist scripture was not pro-idol but anti-religion, some ridiculous semantic argument against calling Buddhism doctrinal because it is only the finger and not the moon and therefore not a religion. (I don't know what the deal is with people of every religion on earth feeling so embarrassed about being religious that they have to get elitist about it and insist that their own religion isn't a religion at all like all the rest are. It's quite universal.)
As for idols, if a deity is vast and superior and mysterious enough to be worthy of worship, then it should be vast and superior and mysterious enough to be impossible to symbolize with any physical object or human conception. There's also something to be said with sincere devotion entailing "cutting out the middle man" as much as is humanly possible.
