Shiva is known by many names such as Viswanatha (lord of the universe), Mahadeva, Mahandeo, Mahasu, Mahesha, Maheshvara, Shankara, Shambhu, Rudra, Hara, Trilochana, Devendra (chief of the gods), Neelakanta, Subhankara, Trilokinatha (lord of the three realms), and Ghrneshwar (lord of compassion). The highest reverence for Shiva in Shaivism is reflected in his epithets 'Mahādeva' ("Great god"; 'mahā' "Great" and "deva" "god"), 'Maheśvara' ("Great Lord"; 'mahā' "great" and 'īśvara' "lord"), and 'Parameśvara' ("Supreme Lord").
