Just for the record, there is some theorization of the topic of emotion in Indian cultural history, but not nearly enough.

Bilimoria, P. and Wenta, A., eds. (2014) Emotions in Indian Thought-systems. New Delhi: Routledge.
Pollock, S. (2016) A Rasa Reader: Classical Indian Aesthetics, Historical Sourcebooks in Classical Indian Thought. New York: Columbia University Press.
Tuske, J. (2011) “The Concept of Emotion in Classical Indian Philosophy,” in The Stanford Encyclopedia of Philosophy. Stanford: Stanford University, pp. 1–30. Available at: http://plato.stanford.edu/archives/spr2011/entries/concept-emotion-india/.

Tuske's conclusions are cogent and compelling, I think, but perhaps challenging for people coming to this for the first time.
