The very idea of religion came up because human beings saw it as a possibility of being in harmony with the whole existence. Once you exist in the physical realm of life, the nature of this realm is such that if we have to transact with each other, my profit is your loss, your profit is my loss. This is the way of physical reality. If we have to deal with this reality, the only way to live is to kill each other. So we brought religion into our lives so that it becomes a medium of harmony. It’s like a lubricant so that there’s no friction between two parts which have to move together.
