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.
What does Aniket mean?
From Sanskrit aniketa (अनिकेत), 'homeless, having no fixed abode', used as an epithet of Shiva (who belongs everywhere and nowhere). The meaning carries an ascetic, all-encompassing sense rather than a negative one.
