菩薩從兜術天降神母胎說廣普經 1.43

1.43

「言性性自空，言有有自空，言無無自空，無自常住，無能令不住，言住住自空，言自相自相空，言陰陰自空，言胎胎自空，乃至道場言行行陰空。以是故，世尊！無有踐跡無踐跡也！」

"To speak of nature, nature is itself empty; to speak of existence, existence is itself empty; to speak of nonexistence, nonexistence is itself empty. Nonexistence is itself eternally abiding, and nothing can cause it not to abide. To speak of abiding, abiding is itself empty. To speak of self-characteristics, self-characteristics are themselves empty. To speak of skandhas, the skandhas are themselves empty. To speak of the womb, the womb is itself empty; up to the bodhimaṇḍa, to speak of saṃskāra, the saṃskāra-skandha is empty. For this reason, Bhagavat, there is neither treading of the path nor non-treading of the path!"
