The Buddha questions Sāriputta at Sūkarakhatalena as to why a monk who has destroyed the corruptions (āsava) should revere the Buddha and his teachings. Sāriputta answers that it is because such a monk has secured freedom from the yoke. “What kind of security is it?” asks the Buddha, and Sāriputta explains that it is security obtained by the cultivation of the five faculties of faith, energy, etc. S.v.233 f.
