One school in Hindu philosophy is called Sankhya, which literary means numbers. So it seeks rationality, like 2+2=4, rejecting 2+2=5. In other words a concept has to go thru rational examination before being accepted or rejected. It is unfortunate that those who now claim to be Hindus and forcing its unrealistic rituals and customs, do not seek truth and rationality in their thinking. And that is damaging to Hinduism.
