Book XVII [The Progress to Lumbinī] of The
Buddha-
1. When the heavenly beings with Brahman at their head and the
Bodhisattvas intent on self-mortification heard this glorification of
the Law uttered by the lion of the Śākyas, they were desirous to hear
again this which is so difficult to find, and they went to the city and
worshipped him, propitiating his favour; in the dark fortnight of the
month Aṣaḍha on the lunar day sacred to Agni, with the moon in the
constellation called Karṇa (?) and on an auspicious day, – he,
remembering the Buddha worlds and being desirous to save all
creatures, set off on his journey, longing for disciples with his father
at their head.
2. The associated Brāhmans, accompanied by the inhabitants of Kāśī
who had gone to the Deer Park, and the mendicants to the number of
thirty, were rendered resplendent by the chief of saints; Kāśikā the
harlot of Kāśī went to the heaven of the gods, after she had
worshipped the Jina and attached her sons to the service of the
glorious one; the conqueror of the world then made thirty rejoicing
officiating priests of Kāśī his disciples, initiating them in the course
of perfect wisdom; and the son of Maitrāyaṇī and Maitra, the
preceptor of hosts of the twice-born, named Pūrṇa, obtained true
wisdom from the chief of saints and became a noble mendicant.
