On the five disadvantages of Madhurā:

the ground is uneven,

there is much dust,

there are fierce dogs,

bestial yakkhas, and

alms are obtained with difficulty (A.iii.256).

The Commentary explains (AA.ii.646) that the Buddha, during a tour, once entered Madhurā, and was on his way to the inner city. However, a certain heretic yakkhiṇī stood before him naked, stretching out her arms, her tongue out. The Buddha thereupon turned back and went to the vihāra, where the people entertained him and the monks.
