首楞嚴義疏注經 10.115

10.115

「又三摩中諸善男子，堅凝正心，魔不得便。窮生類本，觀彼幽清常擾動元，於先除滅色、受、想中生計度者，是人墜入死後無相發心顛倒。」

"Furthermore, all good sons in samādhi whose correct minds are firm and congealed cannot be taken advantage of by demons. When they exhaust the origin of the categories of living beings and contemplate that subtle, clear, constantly fluctuating origin, if they produce calculations regarding the previously eliminated form, sensation, and perception, these persons fall into [the view of] having no characteristics after death, generating inverted intentions."
