首楞嚴義疏注經 10.222

10.222

「是人則墮歸無歸執，無想天中諸舜若多成其伴侶，迷佛菩提，亡失知見。是名第六圓虛無心成空亡果。違遠圓通，背涅槃城，生斷滅種。」

"Such a person then falls into the attachment to taking refuge where there is no refuge. The various Śūnyatās in the heaven of no thought become their companions. Bewildered regarding the Buddha's bodhi, they lose their perceptual insight. This is named the sixth [deviation]: perfect voidness without mind, accomplishing the fruit of empty annihilation. They stray far from perfect penetration, turn their backs on the city of nirvāṇa, and give rise to the seed of utter extinction."
