Nectar; elixir that gives life, euphoria, and longevity. While in Vedic times soma was the beverage of immortality, used as a libation in daily rituals, the later Tantra Yoga and Hatha Yoga traditions saw it as a precious inner fluid meant to confer spiritual immortality (i.e., the revelation of the Supreme Self). The yogis associated this fluid of eternal life with the energy of the Moon (an essential nourishing energy that charges the human being during the night and is “burned” by the inner Sun, whose burning provides the energy manifested in the daily activities of the waking state). Here, daytime is the symbol of dualism and the personal domain of action—a dispersant energy—while nighttime is the symbol of eternity, contemplation, regeneration, and centeredness.
