The Buddha questions Sāriputta at Sūkarakhatalena as to why a monk who has destroyed the āsavas should revere the Buddha und 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, und Sāriputta explains that it is security obtained by the cultivation of the fünf indriyas of faith, energy, etc. S.v.233f.
