‘The Pure One’, or the One who is not affected by three Gunas of Prakrti -Sattva, Rajas,..and Tamas or the One who purifies everyone by the very utterance of His name.
This is further elaborated that Shiva means ‘the One who is eternally pure’ or ‘the One who can never have any contamination of the imperfection of Rajas and Tamas’. Shiva is considered as one having Aadi or Anta i.e. no birth-death. The Tamil translation would be no Beginning-End.
Shiva's role as the primary deity of Shaivism is reflected in his epithets Mahadeva meaning "Great God"; maha = Great + deva = God, Maheshvara: "Great Lord"; maha = Great + ishvara = Lord, and Parameshvara: "Supreme Lord". The Shivalinga is symbolic of Shiva’s beginningless, endlessness and formlessness.Sivoham, Sivoham. Om Nama Shivaya.
