Once there was a person who sought the True Path in the Himalayas. He cared nothing for all the treasures of the earth or even for all the delights of heaven, but he sought the teaching that would remove all mental delusions.
The gods were impressed by the man's earnestness and sincerity and decided to test his mind. So one of the gods disguised himself as a demon and appeared in the Himalayas, singing: "Everything changes, everything appears and disappears."
The seeker heard this song which pleased him very much. He was as delighted as if he had found a spring of cool water for his thirst or as if a slave had been unexpectedly set free. He said to himself, "At last I have found the true teaching that I have sought for so long." He followed the voice and at last came upon the frightful demon. With an uneasy mind he approached the demon and said: "Was it you who sang the holy song that I have just heard? If it was you, please sing more of it."
The demon replied: "Yes, it was my song, but I can not sing more of it until I have had something to eat; I am starving."
The man begged him very earnestly to sing more of it, saying: "It has a sacred meaning to me and I have sought its teaching for a long time. I have only heard a part of it; please let me hear more."
The demon said again: "I am starving, but if I can taste the warm flesh and blood of a man, I will finish the song."
The man, in his eagerness to hear the teaching, promised the demon that he could have his body after he had heard the teaching. Then the demon sang the complete song.
Everything changes,
Hearing this, the man, after he wrote the poem on rocks and trees around, quietly climbed a tree and hurled himself to the feet of the demon, but the demon had disappeared and, instead, a radiant god received the body of the man unharmed.
