Rasa is Kupolė's daughter, in Lithuanian mythology.

Rasa is also a concept in Indian art corresponding roughly with the idea of a dominant emotion. For example:

These fictionalized emotions which we experience through poetry and art are called rasa Aristotle was getting at this idea when he talked about the emotions of pity and fear as essential to tragedy. The Indian theoretician Bharata, however, went much further, positing eight "stable" rasas and 33 "transient" ones:

1. Eros
2. The comic
3. Grief
4. Rage
5. Heroism
6. Fear
7. Disgust
8. Wonder (Amazement)

We won't worry about the transient emotions.
