“The Handsome Monkey King had enjoyed this insouciant existence for three or four hundred years when one day, while feasting with the rest of the monkeys, he suddenly grew sad and shed a few tears. Alarmed, the monkeys surrounding him bowed down and asked, "What is disturbing the Great King?" The Monkey King replied, "Though I am very happy at the moment, I am a little concerned about the future. Hence I'm distressed.” The monkeys all laughed and said, "The Great King indeed does not know contentment! Here we daily have a banquet on an immortal mountain in a blessed land, in an ancient cave on a divine continent. We are not subject to the unicorn or the phoenix, nor are we governed by the rulers of mankind. Such independence and comfort are immeasurable blessings. Why, then, does he worry about the future?" The Monkey King said, "Though we are not subject to the laws of man today, nor need we be threatened by the rule of any bird or beast, old age and physical decay in the future will disclose the secret sovereignty of Yama, King of the Underworld. If we die, shall we not have lived in vain, not being able to rank forever among the Heavenly beings?"
When the monkeys heard this, they all covered their faces and wept mournfully, each one troubled by his own impermanence.”
