[81] Now at that time the walking path (caṅkama) had a low base; it was flooded with water. … "Bhikkhus, I allow it to be made with a high base."
The raised facing collapsed. … "Bhikkhus, I allow three kinds of facing to be built up: a facing of bricks, a facing of stones, and a facing of wood."
Those climbing up were troubled. … "Bhikkhus, I allow three kinds of stairs: brick stairs, stone stairs, and wooden stairs."
Those climbing up fell off. … "Bhikkhus, I allow a railing for holding on."
