Sri Gnanaprasunambika Devi is the consort of Sri Kalahastishwara Swamy (Lord Shiva of Srikalahasti Temple). She is one of the manifestations of Goddess Parvati.
Here is the complete story of the origin and the birth of Sri Gnanaprasunambika Devi…
Lord Shiva initiated Goddes Parvathi with Sacred Panchakshari mantra and asked her to perform Japa with concentration. But She failed to do so He hrew wild and cursed her to born as woman on the earth. Goddess repented for her apse and prayed Lord to relieve her from.
As per the curse in her human birth, she should perform penance and worship Shiva linga near Kailasa Mountain. With the help of sage Narada Maharshi.
In human birth, Parvathi came to Dakshina Kailasa here, performed penance and worshiped Lord. Pleased with her penance and worship, once again Shiva initiated her with Panchakshari. On attaining Panchatkhari Japasiddi (the merits of reciting Panchakshari Mantra), She was accepted as His Consort. Since then She has been worshipped as Gnanaprasunambika. She bestows the Supreme Knowledge upon her devotees.
