Namaste is a respectful form of greeting in Hindu custom, found on the Indian Subcontinent and among the Indian diaspora. It is used both for salutation and valediction. Namaste is usually spoken with a slight bow and hands pressed together, palms touching and fingers pointing upwards, thumbs close to the chest. This gesture is called Añjali Mudrā or Pranamasana. In Hinduism it means “I bow to the divine in you”.The greeting may also be spoken without the gesture or the gesture performed wordlessly, carrying the same meaning.
In the Hindi and Nepalese speaking populations of South Asia, both Namaste (/ˈnɑːməsteɪ/, ; Devanagari: नमस्ते) and Namaskar are synonymously used. In Nepal, people generally use Namaskar for greeting and respecting their elders.
