At that time the monks, after they had bathed in the Naḷaka-pāna lake, had the canes of the Naḷa-plant brought to them by the novices, for needle-cases. And finding them hollow throughout, they went to the Teacher, and asked him, “Lord! we had Naḷa-canes brought for needle-cases. They are hollow throughout, from root to point. How is this?”
“This, mendicants,” said he, “is a former command of mine.” And he told a tale.
This was formerly, they say, a densely-wooded forest. And in its lake there was a water-demon, who used to eat whomsoever went down into the water. At that time the Bodisat was a monkey-king, in size like the fawn of a red deer; and attended by a troop of monkeys about eighty thousand in number, he lived in that forest, preserving them from harm.
Now he exhorted the troop of monkeys, saying, “My children! in this forest there are poisonous trees, and pools haunted by demons. When you are going to eat fruits of any kind you have not eaten before, or to drink water you have not drunk before, ask me about it.”
“Very well,” said they. And one day they went to a place they had not been to before. There they wandered about the greater part of the day; and when, in searching about for water, they found a pond, they sat down without even drinking, and looked forward to the arrival of their king.[297]
When the Bodisat had come, he asked them, “Why, my children, do you take no water?”
“We awaited your arrival,” said they.
“It is well, my children!” said the Bodisat; and fixing his attention on the foot-marks close round the edge of the pond, he saw that they went down, but never came up. Then he knew that it was assuredly haunted by demons, and said, “You have done well, my children, not to have drunk the water. This pond is haunted!”
But when the demon of the water saw that they were not going down into it, he assumed the horrible shape of a blue-bellied, pale-faced, red-handed, red-footed creature, and came splashing out through the water, and cried out, “Why do you sit still here? Go down and drink the water!”
