As per the Kamika Agama, Devi Parashakti receives Upadesa from Bhagavan Paramashiva and she comes down to Kanchi bringing the science of superconsciousness from ShriKailasa. She established the science as a civilization through the Kanchi ShriKailasa Sarvajnapeetam.
As per the Arunachala Puranam, after getting married to Bhagavan Paramashiva, Devi Parashakti asked for the boon of residing in the left half of Bhagavan Paramashiva. Bhagavan Paramashiva guides her to go to Gautama Ashram which is located right across Thiruvannamalai Aadheenam and does tapas. Devi Parashakti attains Enlightenment and merges into Bhagavan Paramashiva becoming Ardhanaareshwara.
She then spreads the Science of Superconsciousness brought from ShriKailasa to Kanchi into Thiruvannamalai. All sampradayas existing today including Shaivism, Vaishnavism, Shaktam, Kaumaram, Vedanta, Siddhanta, Advaita vedanta happened from the most flourishing Kanchi ShriKailasa Sarvajnapeetam. The great rishi, Bodhidharma was initiated and received knowledge of the Science of Superconsciousness from Kanchi Kailaasa Sarvajnapeetam. Adi Shankaracharya, the reviver of Advaita Vedanta sampradaya attains samadhi in Kanchi Kailaasa Sampradaya.
Kamika Agama was flourishing in Kanchi and Thiruvannamalai for eons through the Kanchi ShriKailasa Sarvajnapeetam. As incarnation of Paramashiva, His Divine Holiness has been and is continuing to initiate millions into Living Enlightenment, essence of Kamika Agama through Nithyananda Satsanghs. As the 233rd successor of Kanchi ShriKailasa Sarvajnapeetam, HDH Nithyananda Paramashivam formally institutionalized it into Nithyananda Hindu University in 2000 in the US and Kailaasa Hindu Universities all over the world till date.
