Sree Poornathrayeesa Temple, one of the greatest temples in kerala is situated in Tripunithura, Kochi. The main deity of this temple is Sri Maha Vishnu in Santhanagopala (“savior of infants”) Murthy form. The Lord is seen here sitting in a unique pose with the upper hands holding Sanku (Conch) and Sudarshana Chakram (holy wheel) and lower right hands holds the Padmam (Lotus flower). The Lord is sitting under the shade of five hooded serpant – Ananthan (or the endless). On the back side of Sreekovil, there is a small window from where devotees can get a close look at the idol of Santhana Gopala Moorthy of Sree Poornathrayeesa Temple.
Poornathrayeesa is the combination of 3 words - ‘poorna’ means complete, ‘thraye’ means three, and ‘isa’ means Iswara which means the Lord of Knowledge, or the Lord of the Three Vedas – Rig Veda, Yajur Veda and Sama Veda.
It is believed that Arjuna of Mahabharatha established this temple. There is a Keda Vilakku (lamp which burns always) which is said to be the first lamp lit by Arjuna during the original consecration of the idol. Arjuna collected some gingely seeds and made oil out of the seeds to light the lamp. In memory of this event, the Lord is offered ‘Olpenna” (offering of gingely oil) which is considered as the most important Vazhipadu (offering) in this temple.
It is believed that childless couples are blessed with children on worshipping Sree Poornathrayeesan as the Lord is in the form of Lord Santhana Gopalakrishna.
