What does Soma mean?
Soma is a common alternate name of the Hindu moon god Chandra. Note: in the earliest Vedic texts Soma referred chiefly to a ritual plant and its drink; the lunar sense developed in post-Vedic mythology, so the moon meaning is deity-derived rather than primary.
What does Nirav mean?
From the Sanskrit निरव (nirava), 'soundless, still', formed from nir- ('without') + rava ('sound, noise') — hence tranquil stillness. A genuine, if less common, classical formation.
