Hasta Karaṇas -
Saṅgītanārāyaṇa - Language: Sanskrit
Sangitanarayana is a Sanskrit text on music and dance written in the 17th century by Purusottama Misra, a minister at the court of King Gajapati Narayanadeva of Parlakimidi in Orissa and his instructor in musicology, with the assistance of the king. While the precise date of the Sangitanarayana is not known, its relationship to Purusottama Misra and Gajapati Narayanadeva prompts us to place it in the first half of the 17th century. One of the most valuable and extensive texts on music and dance from eastern India, Sangitanarayana consists of four chapters, the first on vocal music (gitanirnaya), the second on instrumental music (vadyanirnaya), the third on dance and dramatic art (natyanirnaya), and a fourth chapter that provides examples of musical compositions (Suddhaprabandhodharana).
When the fingers are bent in sequence starting with the forefinger and the hand is brought from the side to the chest with the palm facing the front, then it is known as avestita karana of the hand.
But if the movement of the fingers in sequential order is done away from the palm of the hand [and] away from the region of the chest, it is known as udvestita karana [of the hand].
In dvartita [vyavartita], the hand is moved around as in avestita,
while it is known as parivartita when the hand is explained by udvestita.
