What is the benefits of "Namaskar"?

Touch the thumbs to the mid-brow region. This posture awakens the Bhav of surrender in an embodied soul, and  in turn activates the appropriate subtle frequencies of Deities from the Universe.

They enter through the 'Adnya chakra' of the embodied soul and settle in the space parallel to it at the back interior of the head. In this space the openings to all the three channels converge; namely, the Moon, the Central and the Sun channels. Due to the movement of these subtler frequencies in this space, the Central Channel is activated.

Consequently it facilitates the speedy transmission of these frequencies throughout the body, leading to purification of both the gross and subtle bodies at the same time.
