The term Lasya, in the context of Hindu mythology, describes the dance performed by Goddess Parvathi as it expresses happiness and is filled with grace and beauty. She is believed to have danced the Lasya in response to the male energy of the cosmic dance of Tandava performed by Lord Shiva. In a literal sense, Lasya means beauty, happiness and grace.
The Indian classical music terminology talam has been etymologically derived from the union of the dances of both Lord Shiva and Goddess Parvati (Tandavam and Lasyam). The expression of happiness and joy in dance is also termed as Lasyam.
