Sthāyi-bhāva really means the global personality of an individual based on his or her emotional makeup, refined or unrefined. There are eight of these sthāyi-bhāva in the traditional depiction starting with Bharata’s Nāṭya-śāstra. These are rati (love), hāsa (laughter), śhoka (grief), krodha (anger), utsāha (enthusiasm), bhaya (fear), jugupsā (disgust), vismaya (astonishment). Each of these is related to a rasa, i.e., when the fundamental or permanent mood of an individual is excited by hearing a story, etc., then that mood is awakened and experienced directly. That is called rasa.
