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.
What does Raja mean?
From Sanskrit 'rajan' (nominative 'raja'), meaning 'king', ultimately from a Proto-Indo-European root meaning 'to rule, to straighten'. (Note: the identically-spelled Arabic 'Raja' is an unrelated feminine name meaning 'hope'.)
