Krsna performs rasa lila of two varieties, one in the autumn season
and one in the spring season, on vaisakha purnima. Balarama also
performs rasa dance at this time.
In order to keep the gopis in Vrndavana satisfied, Lord Balarama
stayed there continually for two months, namely the months of
Caitra and Vaisakha. For those two months he kept himself among the
gopis and he passed every night with them in the forest of
Vrndavana in order to satisfy their desire for conjugal love. Thus
Balarama also enjoyed the rasa dance with the gopis during those
two months.
