Thay, what do you mean when you say to go back to our religious roots? How can we do that and continue to study and practice Buddhism, which is so practical and helpful?
I think we have to look into our religious roots, because sometimes we are not capable of identifying our spiritual roots. If you are a Buddhist, then you know that Buddha is a root, but you are aware that before the Buddha there was already something — the Buddha was somebody who also had roots. So your roots did not begin with the Buddha. To inquire about the Buddha and the ancestors of the Buddha is important.
