Jhayati

Jhayati in Pali glossary vgl. Dhyana

jhāyati : (jhā + ya) burns; to be on fire. || jhāyati (jhe + a), meditates or contemplates.

According to Buddhaghosa (5th century CE Theravāda exegete), the term jhāna (Skt. dhyāna) is derived from the verb jhayati, "to think or meditate", while the verb jhapeti, "to burn up", explicates its function, namely burning up opposing states, burning up or destroying "the mental defilements preventing [...] the development of serenity and insight."
