~Takshasilâ--Legends--The Four Great Topes~
Seven days' journey from this to the east brought the travellers to the
kingdom of Takshasilâ, which means "the severed head" in the language of
China. Here, when Buddha was a Bodhisattva, he gave away his head to a
man; and from this circumstance the kingdom got its name.
Going on further for two days to the east, they came to the place where
the Bodhisattva threw down his body to feed a starving tigress. In these
two places also large topes have been built, both adorned with layers of
all the precious substances. The kings, ministers, and peoples of the
kingdoms around vie with one another in making offerings at them. The
trains of those who come to scatter flowers and light lamps at them
never cease. The nations of those quarters call those and the other two
mentioned before "the four great topes."
