The Tamil greeting, namaste or namaskar in Northern India.
This is the usual way of saying good morning or welcome: clasp vertically your hands in front of your chest, while giving a bow as a sign of respect.
The higher you raise your hands, the more you bend your head, the greater is the mark of respect for the person in front of you. The ultimate form is to bend down to touch his feet in reverence, or even get face down on the ground in worship.
Here in India, we do not shake hands, we do not kiss, we avoid all physical contact.
VANAKAM, welcome to SITA !
