“What is ignorance? Virtuous man, since beginningless time, all sentient beings have had all sorts of delusions, like a disoriented person who has lost his sense of direction. They mistake the four great elements as the attributes of their bodies, and the conditioned impressions of the six sense objects as the attributes of their minds. They are like a man with an illness of the eyes who sees an [illusory] flower in the sky, or a second moon.
“Virtuous man, there is in reality no flower in the sky, yet the sick man mistakenly clings to it. Because of his mistaken clinging, he is not only deluded about the intrinsic nature of the empty space, but also confused about the arising of the flower. Because of this false existence [to which he clings], he remains in the turning wheel of birth and death. Hence this is called ignorance.
“Virtuous man, this ignorance has no real substance. It is like a person in a dream. Though the person exists in the dream, when [the dreamer] awakens, there is nothing that can be grasped. Like an [illusory] flower in the sky that vanishes into empty space, one cannot say that there is a fixed place from which it vanishes. Why? Because there is no place from which it arises! Amidst the unarisen, all sentient beings deludedly perceive birth and extinction. Hence this is called the turning wheel of birth and death.
“Virtuous man, one who practices Complete Enlightenment of the causal ground of the Tathagata realizes that [birth and extinction] are like an illusory flower in the sky. Thus there is no continuance of birth and death and no body or mind that is subject to birth and death. This nonexistence of [birth and death and body and mind] is so not as a consequence of contrived effort. It is so by its intrinsic nature.
