When two Sūcimukha hastas are moved aside from the front simultaneously, it will be Sūcyāsya hasta.
This hasta denotes saying 'what am I to do'?, yearning for the beloved, saying 'everything' and 'look here'.
Sūcyāsya: The hands which are in the Catura Hasta are extended obliquely with the elbows being slightly bent.
First the patāka hastas perform vyavartana and parivartana in caturasra position. They are turned into sreciarpaṡīrsha hastas in the same position.
Then they become sūçīmukha hastas which are extended to the sides transversely and alternately. These are the sūcyāsya hastas as experts of dance explicated.
If the two Sarpasirasas are extended a little with the two elbows contracted, it is Sucyasya hasta.
