Note 4 — Chapter VIII · WOO-CHANG, OR UDYÂNA. MONASTERIES, AND THEIR WAYS. TRACES OF BUDDHA.
James Legge translation
There is a tradition that when Buddha came to North India, he came at once to this country, and that here he left a print of his foot, which is long or short according to the ideas of the beholder (on the subject). It exists, and the same thing is true about it, at the present day. Here also are still to be seen the rock on which he dried his clothes, and the place where he converted the wicked dragon.4 The rock is fourteen cubits high, and more than twenty broad, with one side of it smooth.
