' And when the boy Vipassi was born, brethren, he looked forward with unblinking eyes, like the gods in the heaven of Delight. Now it was because of this, people exclaiming " Vipassi, Vipassi " — a Seer, a Seer! — that this became his name 3. And again, brethren, while Bandhuman raja was sitting as judge, he would take the boy on his hip and so lay down the law as to the cases arising till verily the boy, thus seated on his father's hip, and continually considering, would also determine the points of the matter according to justice 4. Then at the thought "It is the babe who is judging cases arieht " ever more and more did that word " a Seer, a Seer" become used as his name.
