Prologue. The Diamond that cuts through illusion is the last sutra of World-Honored One. It contains so much valuable wisdom. Staying in Anathapindika’s garden in the Jeta Grove near Sravasti, the Buddha awakens the Great Integrity. He teaches to get out of ignorance and agony to find the original nature. He urges to stop rational thinking with serene sensibility and wisdom. All composed world is like a dream or an illusion, like dew drops or lightning flashes.
