From the website of Reverend Diane Jensen:
"Namaste" is the Sanskrit word that means "I bow to the divine in you."
What a lovely expression!
From Aadil Palkhivala:
We bring the hands together at the heart chakra to increase the flow of Divine love. Bowing the head and closing the eyes helps the mind surrender to the Divine in the heart. One can do Namaste to oneself as a meditation technique to go deeper inside the heart chakra; when done with someone else, it is also a beautiful, albeit quick, meditation.
For a teacher and student, Namaste allows two individuals to come together energetically to a place of connection and timelessness, free from the bonds of ego-connection. If it is done with deep feeling in the heart and with the mind surrendered, a deep union of spirits can blossom.
When spoken to another person, it is commonly accompanied by a slight bow made with hands pressed together, palms touching and fingers pointed upwards, in front of the chest.
