The Long Āgama Sūtra 27.56

27.56

「復次，大王！如來、至真、等正覺出現於世，入我法者，乃至三明，滅諸闇冥，生大智明，所謂漏盡智證。所以者何？斯由精勤，專念不忘，樂獨閑靜，不放逸故。云何，大王！此非沙門現在果報也。」

“Furthermore, great king, the Tathāgata, Arhat, and Rightly and Fully Awakened One arises in the world. Someone who enters my teaching … three insights destroy the shadows and produce the great radiance of knowledge, which is the knowledge realized by ending the contaminants. Why is that? These things come from diligence, focused mindfulness that isn’t lost, delighting in quiet seclusion, and not being careless. How is it, great king? Is this not an ascetic’s reward attained in the present?”
