We use these sounds in the Vedic Astrology Club as part of the opening chants to invoke blessings from enlightened siddha Maharishi Brghu:

Brghu

He is well known for performing fire ceremonies, for teaching Vedic astrology and for being the father of Venus. We ask his blessings to help us succeed with our studies and practice of Vedic astrology. We ask him to help us with remedies.

Dr. Pillai has noted that it is said Brghu also had incarnation as Lao Tzu in the Chinese tradition and as Einstein in the West.
