In sanskrit the word "NAMAS" means bow and "TE" means to you. Namaste means "I bow to you".
Namaste is the most popular Indian greeting performed by pressing two hands together and holding them near the heart with the head gently bowed as one says "Namaste". There is great symbolism behind this greeting. Both hands depict duality of positive and negative, and bringing the hands together affirms the singleness in the world.
The whole act communicates "You and I are one".
