In India, when people greet one another they put their palms together and bow, saying namaste, "I honor the divine within you." It is a way of acknowledging your Buddha nature, who you really are. Some believe that the Western handshake evolved to demonstrate friendliness and safety, to show that you are not holding any weapon. But the greeting namaste goes a step further, from "I will not harm you" to "I see that which is holy in you." It creates the basis for sacred relationship.
