A Man's Head (Siva's?) Emerges from the Head of a Snake (Kundalini?)

Possibly representing presence of siva within the Kundalini shakti.

Image of Satguru Sivaya Subramuniyaswami
As you sit in meditation in a darkened room, practice directing your consciousness inward, to the center of your brain. If you are able to perceive light within your body, you are on the path to immortality.
—Gurudeva
