"Chali" or "Chari" is the basic dance movement in Manipuri "Ras" dances. The repertoire and underlying play depends on the season. The dances are celebrated on full moon nights, three times in autumn (August through November) and once again in spring (March or April). The "Vasant Ras" is timed with the Hindu festival of colors called Holi, while others are timed with post-harvest festivals of Diwali and others. The plays and songs recited during the dance performance center around the love and frolics between Radha and Krishna, in the presence of "Gopis" named Lalita, Vishakha, Chitra, Champaklata, Tungavidya, Indurekha, Rangadevi and Sudevi. There is a composition and dance sequence for each Gopi, and the words have two layers of meanings, one literal and other spiritual. The longest piece of the play focuses on Radha and Krishna. The dancer playing Krishna expresses emotions, while the body language and hand gestures of the Gopi display their feelings such as longing, dejection or cheer.
