Grammatical Analysis
Asekha: [m.; adj.] a non-learner; one beyond training; an adept; master. Formed by the negative prefix a (not/no more) + sekha (learner/trainee). Signifies one who has fully completed the entire spiritual curriculum.
Orthodox Definition
An Asekha is the absolute antithesis of the puthujjana and the ultimate fulfillment of the sekha. This designation applies exclusively to the eighth noble individual: the Arahat who stands firmly in the Supramundane Fruition of Arahatship (arahatta-phalaṭṭho).
An asekha has completely finished the task of spiritual purification. Because they have uprooted all ten fetters and destroyed the last traces of ignorance and influxes (āsavakkhaya), they no longer have any further training rules to master, defilements to suppress, or insight paths to cultivate.
The mind of an asekha operates in a state of flawless, unshakeable equanimity. Their choices no longer construct kusala or akusala kamma; their mental actions are classified entirely as functional (kiriya-citta), passing away cleanly without generating any karmic residue inside saṃsāra.
