The two hands are to have Kutila (oblique) movement after touching the opposite shoulder elbow and hands. Then the palms are moved and turned towards the back. This is known as Āviddhavakraka.
Āviddhavakraka—The two hands are to have a graceful (kuṭila) movement after touching [successively] the opposite shoulder, elbow and hands, and the palms [of the hands] moved are to turn towards the back.
Two hands with the elbows curved and the palm of the hands bent upwards are called Āviddha.
Āviddhavakatra: The elbows, the shoulders and the hands which are in the Arāla Hasta are moved pointing downwards.
Aviddhavakra: If the upper part of hand is twisted in the aviddha hasta, it is aviddha vokra.
Pataka hasta amorously traverses the bent shoulders, elbows and arms in that order to form āviddhavakra hastas.
If the two Aralas are held up with the two elbows joined together, and then are made to face down tremblingly, it is Aviddhavaktra
If the self same hands are reversed and displayed with sportful movements of the forearm, elbow and shoulder [it becomes] āviddhavaktra.
Moving patāka hands quickly inward [in vyavrtti] with palms facing downwards while the arms, the elbows and the shoulders are moved gracefully, it is called aviddhavaktra hand [gesture]. Experts say that it is used in throwing or walking.
