He who drinks the clear stream of the "liquor of the Moon" (soma) falling from the brain to the sixteen-petalled lotus (in the heart), obtained by means of Prâna, by applying the tongue to the hole of the uvula and meditating on the great power (Kundalinî), becomes free of disease and tender in body, like the stalk of a lotus, and this yogî lives a very long life.
