Sage Vamadev was a great devotee of lord Shiva from his birth. He never used to remain at a place for long. One day he had gone to a mountain peak named Kumar, which was situated towards the south of Sumeru Mountain. He met Kartikeya who revealed to him that Pranav Mantra directly signifies the almighty God. Kartikeya also told him that with the help of that mantra a person can attain lord Shiva – who liberates from all the bondage of life.
Though, Vamadeva himself knew about the power of Pranav mantra yet he requested Kartikeya to shed some more light on it. Kartikeya told him that any one could have the proximity of lord Shiva, by the help of the means prescribed in the Shrutis and the Samritis.
Regarding the methods of Shiva’s worship, Kartikeya told Vamadeva that though Sadashiva was one, yet he was known by various names like Maheshwar, Rudra, Brahma and Vishnu. Mahesh was created from the thousandth part of Sadashiva. The goddess of all illusions – Bhagawati dwells in the left side of Sadashiva, therefore he is the lord of all the actions of the universe. Sadashiva plays his desire acts by indulging in creation, nurturement and annihilation of this world.
