Note 9 — Chapter XXV · VAIŚÂLÎ. THE TOPE CALLED ‘WEAPONS LAID DOWN.’ THE COUNCIL OF VAIŚÂLÎ.
James Legge translation
It was by the side of the ‘Weapons laid down’ tope that Buddha, having given up the idea of living longer, said to Ânanda, ‘In three months from this I will attain to pavi-nirvâṇa;’ and king Mâra9 had so fascinated and stupefied Ânanda, that he was not able to ask Buddha to remain longer in this world.
