Lasyam

• The term Lasyam, in the context of Hindu mythology and Indian dance, describes the dance performed by Goddess Parvati since it expresses happiness and is graceful and feminine. 
• This is because the word Lasyam literally means beauty, happiness, joy and grace, in Sanskrit. 
• Lasyam is the feminine counterpart of the masculine Tandava and Parvati is believed to have danced the Lasyam in response to the vigorous Tandava performed by Lord Shiva, to balance it out. 
• The Bharatanatyam term 'Thala' has been claimed to have been derived from the union of the first syllable of the words Thandavam and Lasyam, since they are important elements in the dance.
• Parvati taught the Lasyam dance to Usha, the daughter of Banasura, who then taught it to the gopis of Vrindavana, who then subsequently spread it to more people.
