复次舍利子，我证菩提无为无性。何故名曰无为无性？
舍利子，是菩提性非眼识所识，乃至非意识所识。言无为者无生无灭，亦无有住，三相永离，故名无为。
《大宝积经》卷39
In addition, Sariputra, I have realized that the Bodhi is thenon-active nothingness nature. Why is the nature called non-activenothingness? Sariputra, the nature of the Bodhi is not thediscriminating function of the eye-consciousness,and even is not thediscriminating function of the mind-consciousness. Non-activenessmeans that the Bodhi is without arising and ceasing, and is withoutdwelling in anything either. The Bodhi is always away from the threeappearances; therefore, it is called non-activeness.
