[468] "What do you think, great king? If a sudda (menial) should prosper in wealth, or grain, or silver, or gold, would even a sudda rise before him and retire after him, attend upon his bidding, behave agreeably, and speak pleasantly to him? Would even a khattiya (noble) … even a brāhmaṇa (brahmin) … even a vessa (merchant) rise before him and retire after him, attend upon his bidding, behave agreeably, and speak pleasantly to him?" "Worthy Kaccāna, if a sudda should prosper in wealth, or grain, or silver, or gold, even a sudda would rise before him and retire after him, attend upon his bidding, behave agreeably, and speak pleasantly to him. Even a khattiya … even a brāhmaṇa … even a vessa would rise before him and retire after him, attend upon his bidding, behave agreeably, and speak pleasantly to him."
