The Radiant Buddha said:
Regard this fleeting world like this:
Like stars fading and vanishing at dawn,
like bubbles on a fast moving stream,
like morning dewdrops evaporating on blades of grass,
like a candle flickering in a strong wind,
echos, mirages, and phantoms, hallucinations,
and like a dream.
–The Eight Similes of Illusion, from the Prajna Paramita Sutras
