Hollow Reed Grass
In those days, there was a water demon living in a lotus pond. It had eaten many humans and animals that went into the pond.
One day, there was a group of monkeys, which had about eighty thousand monkeys. This group was leaded by a great monkey.
The great monkey said to all monkeys “Normally, in a big forest, there was some poison plants. Same as ponds, they usually owned by water demons. When you find any fruit you never eat or pond you never went into, you must tell me first.”
Some monkeys arrived at the pond and waited for the great monkey. When the great monkey arrived, he asked “Why didn’t you go down into the pond ?”
“We are waiting for you.” the monkeys replied.
“That’s good.” the great monkey said and looked around the pond.
Found that there were only footsteps that head down into the pond, he said “This pond was owned by a water demon. Each of you should find a reed grass for drinking water.”
Because of this, all monkeys were safe from a water demon.
The water demon finally reincarnated as Devadatta. The great monkey finally reincarnated as the Buddha.
