The recital of "Ayathu Sivalokam" in the nearby Arattupuzha temple is very old, perhaps more than 1500 years and this suggests that this Vamana temple is equally old. The other deities worshiped here are Ganesa, facing south and 'Swamy' facing southeast. Goddess Annapoorneswari is adorned in the northeast pillar. Sampoorna Yajurveda Yajna or Othu Kottu is the primary festival here and it is held every three years in the months of July to November.

Vamana and Mahabali. dhivya prabandham - koyil.org

The king of Asuras Mahabali, gained a lot of mystical power  not only by leading a virtuous life but also by conducting Yajnas and other rituals and ultimately he became a master of three worlds - Pathala (underworld), Akash (sky), and Bhoomi (earth) and nobody could challenge his supremacy as the lord bestowed on him many boons. Driven by ego, arrogance and vast power, he misused his mystic power.   He overpowered the lord of heaven, Indira. A situation arose for Lord Vishnu to correct his ego and his over- bearing nature. Mahabali was a king with a charitable disposition and would grant anything if a person approached him for help.  Lord Vishnu, took the guise of a Vamana, (a dwarf), a short Brahmin. It was the first avatar of Vishnu, in a  human form as the son of Kashyapa and Aditi (born in the month of Bhadrapatha). He is also sometimes known as Upendra or Indranuja. Vamana, carrying a wooden umbrella, asked Mahabali to grant him three strides of land for his use and Mahabali granted his request, despite warning from his guru Sukracharya. Vamana took his original physical form and grew in size touching the heaven and earth. With first and second strides, Vishnu measured the sky and the earth. Mahabali who stood there tongue-tied asked the lord to put his foot on his head for the third stride as he had to keep up his word. By doing so, lord Vishnu made Mahabali realize his folly and get rid of his arrogance, pride, and presumption. He also gave him immortality for his benevolence. The moral is: "To succeed in life, one must avoid too much ego and pride. Further, wealth should not be taken for granted to dictate terms with other people, for wealth will never stay with a person permanently".

As for this temple, here  Vamana (lord Vishu)  blessed king Mahabali for granting his request without going back on his promise. The lord was much pleased with the charitable nature of the demon king. The deity in this temple is blessing the king Mahabali.  Mahavishnu further blessed Mahabali, that he would be the ruler of the earth in the following age or Yuga. Those who surrender to the lotus feet of the deity will get his blessings and be from sins.

The temple is under the control of three Uranmakkar (people who have a hereditary right to the temple). They are  Alakkattu Mana, Pattachomarayath Mana, and Akkarachittur Mana.
