Ja 143 The Story about Shining Forth
(Virocanajātaka)
In the present Devadatta makes himself out a Buddha, but loses all his disciples in a stroke. The Buddha tells a story of how a jackal wanted to emulate a lion and soon came to destruction (full story).
1. Lasī ca te nipphalitā, matthako ca padālito,
Sabbā te phāsukā bhaggā, ajja kho tvaṁ virocasī ti.
Your brains are split open, and your head is smashed in, all your ribs are broken, today you did shine forth.
Split open means gone out of the head.
