The introductory chapter of the Jātaka Commentary.

It gives the story of the Buddha in three sections:

the distant cause (Dūre-nidāna) from the time of his birth, as Sumedha, up to his birth in the Tusita world;

the recent cause (Avidūre-nidāna) from his death in Tusita and his birth as Siddhattha, son of Suddhodana, up to his Enlightenment;

and the present cause Santike-nidāna, which contains his story up to the dedication of Jetavana by Anāthapiṇḍika. J.i.1-94.
