首楞嚴義疏注經 6.363

6.363

「汝以婬身求佛妙果，縱得妙悟皆是婬根，根本成婬，輪轉三塗必不能出，如來涅槃何路修證？」

"If you seek the wonderful fruit of the Buddha with a lustful body, even if you attain wonderful awakening, it is entirely rooted in lust; with the root becoming lust, you will turn in the three wretched paths and definitely be unable to escape. By what path could the Tathāgata's nirvāṇa be cultivated and realized?"
