The sub-deities of Vamana temple are Bhagavati, Sasthavu, Gopalakrishna, Nāga, Brahmarakshasa and Yakshi. The Brahmarakshas shrine is located in the outer complex, along with a Banyan-tree god (ആൽദേവത) and the Sarpa Kavu. Surrounding the inner complex walls is a series of thousands of lamps called "Chuttuvilakku" which translates to 'surrounding lamps'. There are two ponds associated with the temple, one is the "Kapilatheertham" located closer to the temple on the Northern side of the sanctum sanctorum, and is accessible only to priests. The other pond is located on the Northern side outside the temple walls, and is used regularly during the "Aaraattu" ceremonial bath of the idol during Onam celebrations.
