is a highly venerated stone slab, enshrined in a special structure in the inner
prakaram of the temple. It is said that Adi Sankara stayed here for sometime,
meditating on MOTHER Parasakti
during his digvijaya yatra. MOTHER Mookambika appearing then in his dream, asked
him to install her in this sanctum. He obeyed the divine injunction at once. The
place where he got that divine command is now worshipped with special rituals
during Navaratri, lasting for 9 days. This is closed after that final festival.
