The Buddha questions Sáriputta at Súkarakhatalena as to why a monk who has destroyed the ásavas should revere the Buddha and his teachings. Sáriputta answers that it is because such a monk has secured freedom from the yoke. "What kind of security is it?" asks the Buddha, and Sáriputta explains that it is security obtained by the cultivation of the five indriyas of faith, energy, etc. S.v.233f.
