It is an important festival of the temple conducted in the Malayalam month Vrichikam (November – December). It begins on the star Chothy and ends with the star Thiruvonam. The festival is conducted jointly by Devaswom and Poornathrayeesa Seva Samgam. It is celebrated on a large scale along with proper Thanthric rituals. This is a national festival not restricted to the level of a temple festival. It is celebrated by one and all irrespective of caste, creed or religion. People from all walks of life co-operate and receive the blessings of Poornathrayeesa. Fifteen decorated elephants are used in the morning and evening functions. Panchari Melam produced by the most popular artists is a sumptuous feast for all lovers of art. Panchari Melam of Tripunithura is famous throughout the country just like “Pandi Melam” of Thrissur Pooram. The music from the wind instrument “Kurumkuzhal” on the day of star “Thrikketta” is highly appreciated by all. The temple atmosphere is always filled with music concerts, Kathakali, Ottamthullal, and different forms of dance including folk dances and other types of competitive activities. Fireworks are not important for the festival because it is believed that loud noise is not liked by the Lord. Elephants and their procession are most liked by the Lord and the expense is shared by many as an offering to Poornathrayeesa. This is a special offering for the long life, prosperity and education of children. The fruits offered during “Para” festival is given to elephants as a mark of attachment to elephants. Both people and elephants enjoy taking sweet food. This happiness will please the Lord. The important days of the festival start on the day of star “Thrikketta”. Vilwamangalam who reached the temple on that day found that God was not present in Sreekovil. When the Swamiyar came out, procession of elephants had already started. He saw children playing on the elephant and the Lord was deeply involved in this play. The Lord sitting on the elephant blessed Swamiyar. The children playing on the elephant may be the children of Santhana Gopala Brahmin or the Gopala of Vilwamangalam, God only knows. Remembering these holy instance devotees worshipped the Lord on the elephant and returned after getting his blessing. It is believed that worshipping the Lord on this auspicious day is equivalent to worshipping him for the whole year. This belief increased the number of devotees visiting the temple on this day and the festival became more popular and attractive. Devotees worshipped the Lord encircled by the dazzling brilliance of gold and diamonds seated on the elephant. They drop money and other items into the gold vessel as offerings and return with increased devotion and happiness. Most of the oil lamps of the temple are lighted during festival days Sreekovil and other important holy spots are decorated with flowers. Light from the huge bronze lamp post on the eastern side fills the hearts of all devotees with happiness. The illumination of the whole temple is a sight which will stick to the mind. Lighting the temple lamps is considered to be a sacred ritual.
