Origin story
The Kollur temple tradition tells of the goddess who killed the demon Mookasura and who blessed Adi Shankara. She is worshipped as a form of Parvati and as the source of the arts and learning, and Kerala devotees make annual pilgrimages to Kollur and keep Mookambika shrines at home.
Mookambika represents the creative energy of Adi Parashakti and is especially beloved in Karnataka, Kerala and Tamil Nadu. The Sri Chakra, the book and the veena express wisdom and the arts, so that the goddess combines the grace of Saraswati with the power of Durga.
