With Mahākassapa
So I have heard. At one time the Buddha was staying near Rājagaha in the Bamboo Grove, the squirrels’ feeding ground. Now at that time Venerable Mahākassapa was staying in the Pipphali cave, and he was sick, suffering, gravely ill. Then after some time he recovered from that illness. It occurred to him, “Why not enter Rājagaha for almsfood?”
