By observing the form (ākṛti), movement (ceṣṭā), signs (cihna), and type (jāti) of a gesture, the wise (actor) should then, through personal reflection, perform the hand-gestures accordingly.
There is no meaning in drama which cannot be expressed by hand gestures. Whatever form is commonly observed (in real life), that has been extensively represented through them.
There are also other conventional (laukika) hand gestures connected with meanings; these too should be employed freely in accordance with the Sentiments (rasa), Psychological States (bhāva), and Movements (ceṣṭita).
देशं कालं प्रयोगं चाप्यर्थयुक्तिमवेक्ष्य च । हस्ता ह्येते प्रयोक्तव्याः नृणां स्त्रीणां विशेषतः ॥ १६५॥
Taking into account the place, time, dramatic context, and the intended meaning, these hand gestures should be used, especially by men and women actors.
