The purnima or full moon of Damodara month is the second full moon of the autumn season, and rasa lila is again celebrated. This second rasa yatra is celebrated more in Bengal, whereas the first one is celebrated more in Vrndavana.
On this day one should perform full worship of Radha and Krsna with many flowers, and place them in a rasa mandapa surrounded by the gopis.
Sri Krishna Vasant Rasa is similar excepting that it is in the Spring (Vasant), at this time everyone dresses in yellow. On this full moon night the devotees usually leave out pots of sweet rice payasam for the Lord to enjoy during His rasas.
