Lord Shiva Prayer - II
This mantra is a prayer to Lord Shiva who is addressed as Sankara and Trayambaka. Sankara means giver of blessings: (sana = blessings, Kara = the Giver). Trayambaka is the three eyed one, where the third eye signifies the giver of knowledge, which destroys ignorance and releases us from the cycle of death and rebirth.

Kalagni - Rudraya Nil - Kanthaya Mrityunjaya
Sarvesvaraya Sadadhivaya
Sriman Mahadevaya Namah.
Meaning:
Om. I bow down to Lord Shiva, who is the creator and protector of the universe, who is the greatest among Gods, who has three eyes, who is the annihilator of all the three worlds, one whose throat is blue, who is the conqueror of death, who is the Lord of all, who is propitious who is possessed of all marks of greatness and who is the greatest among Gods. To him my prostration.

Naagendra haaraaya thriloochanaaya bhasmaangadhaaraaya maheshwaraaya
Nityaaya shudhdhaaya digambaraaya tasmai nakaaraaya namahshivaaya
Meaning:
Salutations to Shiva who wears a serpent as garland, who is three-eyed, whose bare body is covered with ashes, who is forever pure and the very embodiment of sacrifice.

Shiva Dhun:
Shivo Bhokta, Shiva Bhojya Shivo Karta,
Shivah Karma Shivah Karanatmakah
Meaning:
Shiva is the experiencer and the highest object of experience. Shiva is the goal of Sadhana. There is nothing apart from Shiva. There is nothing other than Shiva. Whatever there is, is Shiva. There is nothing, which is not Shiva. There is no place, which is not Shiva. There is no time, which is not Shiva. To be aware of this is to be aware of Shiva.
