Rasa-abhinaya

Indian art evolved with an emphasis on inducing special spiritual or philosophical states in the audience, or with representing them symbolically.

Of particular concern to Indian drama and literature are the term 'bhAva' or the state of mind and 'rasa' (Sanskrit रस lit. 'juice' or 'essence') referring generally to the emotional flavors/essence crafted into the work by the writer and relished by a 'sensitive spectator' or sahṛdaya or one with positive taste and mind.

The Rishi Praskanva insists (Rig Veda I.46.6) that the sources of knowledge some of which are open and some hidden they are to be sought and found by the seekers after Truth, these sources are not available everywhere, anywhere and at all times. In this context Rishi Agastya (Rig Veda I.187.4) stating thus –
