Narial purnima is a very important festival, especially for those people who depend on the sea for their life. It is on this day that the sea god Varun is worshipped. On this day coconuts are offered to the Sea God and thus the name goes as Narial Purnima or the coconut full moon. The festival falls on the time of retreating monsoons.

The decorated coconuts are thrown in the water with prayers of a a plentiful fish catch.

A coconut supposedly has three eyes and is a represntation of Lord Shiva, the three eyed God. Coconut is therefore considered to be auspicious for offering to Gods. A coconut is broken in front of the deities before taking up a new task in hand. Coconut is important for all religious occasions. Thus the coconut is considered appropriate for offering to the Sea God. This practice of drawing with the rice solution on the mud washed floor is called Navami.
