There is no restriction of the number of Gopis in the Ras-dances. Also there is no restriction of the duration of the performance. The Guru (termed as Oja/Rasdhari) and Shutradhari should take as much time as they think it necessary for arousing the feelings of rasa, raga, anuraga, bhava, bibhava, etc. within the hearts of the Gopis as well as in the hearts of the audience. Waiting for Shri Krishna, calling his name, decorating for this satisfaction are all the important steps sung by the Gopis shedding tears on the chicks.
There are different kinds of Ras-dances. They are:
1. Maharas - perforemd in the full moon day (purnima tithi) of Kartik (October-November) based on Shrimad Bhagavata Panchyadhyaya.
