"Eyes play a very central role in the abhinaya in Koodiyattam. The eye training is very laborious and so is the process of putting on the eye make-up before the performance. We also use chundapoo , the ovary of a special flower, to put into the eye before the performance in order to make them bloodshot and strong."
