Fear, confidence, sadness, elation are all associated with the “mindest” at the given moment. The mindset here is not a kilesa or upakilesa, but arise DUE TO kilesa and upakilesa. Elation is not joy (piti), but a “state of mind” like sadness.
Those can become one’s gati (bhavanga) for the next life, if the mindset at the cuti-patisandhi moment is one of those.
– Fear and sadness are associated with births in lower realms.
– Confidence and joy associated with births in higher realms.
– A neutral state of mind (upekkha) can be associated with brahma realms and optimized for an Arahant.
This is why all beings in lower realms have subconscious fear and/or sadness. Those in higher realms have a pleasant state of mind in bhavanga.
Bhavanga is an important concept: “Bhava and Bhavanga – Simply Explained!” and “State of Mind in the Absence of Citta Vithi – Bhavanga“.
