The outline structure of saraswati kolam:
The name Saraswati came from "saras" (meaning "flow") and "wati" (meaning "a woman"). So, Saraswati is symbol of knowledge; its flow (or growth) is like a river and knowledge is supremely alluring, like a beautiful woman.
Saraswati is worshipped as the goddess of knowledge, learning and the arts. This is an important day for schools, musicians, dancers and artists. This kolam is drawn to increase the memory power and to seek the blessings of the goddess. It's ideal to draw five lotus with rice flour below this kolam and worship the goddess.
