Note 7 — Chapter XXV · VAIŚÂLÎ. THE TOPE CALLED ‘WEAPONS LAID DOWN.’ THE COUNCIL OF VAIŚÂLÎ.
James Legge translation
Thus Śâkyamuni had been one of the thousand little boys who floated in the box in the Ganges. How long back the former age was we cannot tell. I suppose the tope of the two fathers who became Pratyeka Buddhas had been built like the one commemorating the laying down of weapons after Buddha had told his disciples of the strange events in the past.
