On Yuan Chwang's Travels in India, 629–645 A.D. v1.c15.91

v1.c15.91

To the south of the Accepting-invitation Tope, the pilgrim proceeds, was the place at which king Virūḍhaka, on his way to destroy the Sakyas, saw the Buddha, and turned back with his army. When Virūḍhaka ascended the throne, Yuan-chuang relates, he raised a great army and set out on the march [from Śrāvastī to Kapilavastu] to avenge a former insult. A bhikshu reported the circumstance to the Buddha; who thereupon left Śrāvastī, and took his seat under a dead tree by the roadside. When the king came up he recognized Buddha, dismounted, and paid him lowly reverence. He then asked the Buddha why he did not go for shade to a tree with leaves and branches. "My clan are my branches and leaves", replied Buddha, "and as they are in danger what shelter can I have?" The king said to himself—"The Lord is taking the side of his relatives — let me return". So he looked on Buddha moved with compassion, and called his army home.
