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'.)
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.
