首楞嚴義疏注經 7.154

7.154

上明三種相續，今明二種顛倒。以眾生顛倒即攝業果故，如前文云「汝但不隨分別世間、業果、眾生三種相續，三緣斷故三因不生，則汝心中演若達多狂性自歇，歇即菩提。不從人得。」故云顛倒不生即真三昧。

Above, the three kinds of continuity were clarified; now, the two kinds of inversion are clarified. Because the inversion of sentient beings subsumes karmic fruits, as the earlier text states: "If you simply do not follow the three kinds of continuity of the world, karmic fruits, and sentient beings, because the three conditions are severed, the three causes do not arise; then the madness of Yajñadatta in your mind will cease of itself, and cessation is bodhi. It is not obtained from another." Therefore it says that when inversion does not arise, that is true samādhi.
