Why do you have to put your hands together when praying?

Folding shows concentration and respect for worship. This is a ritual that has existed in India since ancient times, and Buddhism has also been inherited. Indians believe that the right hand is sacred and the left hand is unclean, so they have the habit of using their hands separately; But if the two hands are combined into one, it is the unity of human sacred face and unclean face, thus showing the true face of human beings.
