On Yuan Chwang's Travels in India, 629–645 A.D. v1.c9.s2.9

v1.c9.s2.9

The P‘usa as brahmin student, variously named Megha, Su-medha and otherwise, on his way to see Dīpankara Buddha met a maiden carrying seven lotus flowers for the service of a shrine in the palace grounds. The P‘usa bargained with the maiden for five of her flowers that he might have them to throw on the Buddha as he passed in procession. At the spot where the flowers were bought, an act involving great consequences in the distant future, king Asoka had built a tope. It is remarkable that the Pali Jātaka does not make any mention of the purchase and offering of the lotus flowers.
