[1137] "A brahmin envoy is not to be slain — Cetaputta, listen to me — therefore indeed one does not slay an envoy: this is an ancient law. All the Sivis have relented; his father longs to see him, and his mother is frail: before long her eyes will fail. I am the envoy sent by them — Cetaputta, listen to me — I shall lead the prince back; if you know, tell me."
