Ambalatthika-rahulovada Sutta: Instructions to Rahula at Mango Stone
“I have heard that on one occasion the Blessed One was staying near Rajagaha, at the Bamboo Grove, the Squirrels’ Feeding Ground.
At that time Ven. Rahula was staying at the Mango Stone. Then the Blessed One, arising from his seclusion in the late afternoon, went to where Ven. Rahula was staying at the Mango Stone. Ven. Rahula saw him coming from afar and, on seeing him, set out a seat & water for washing the feet. The Blessed One sat down on the seat set out and, having sat down, washed his feet. Ven. Rahula, bowing down to the Blessed One, sat to one side.”
