Trikarthika Utsavam is the annual festival celebrated at Kumaranalloor
Bhagavathy Temple, 6 km from Kottayam, in the month of Vrischikam (November-December).
The main highlight of the celebration is the Karthika Pooja and Karthika
Vilakku, i.e the display of lights. There is a story connected with these
rituals. It is said that the Gods of Udayanapuram and Thrissur Vadakkunnathan
temples were charmed by the beauty of the Devi while she was returning
after her Karthika bath. The Gods came out of their temple, stood over
the compound wall of Kumaranalloor Temple by affectionately looking at
her. The temple priest, in search of the Gods met them on the walls at
the southern end of the temple. And from that day onwards Karthika Pooja
is performed by keeping lights on the walls of the temple.
