Falling into a swift current when a rope breaks
The gatha says:
Grasping the boat afloat in the flow, he crossed over suffering and misery.
His clothes were drenched, his feet were cut, and his blood stained the river.

They went to an inn, but had to stay out in the cold, for Sanghans were not accepted.
