注大乘入楞伽經 4.91

4.91

言化佛，但隨順愚夫妄起之見，作種種言說，說自相共相，令知不實法故。非非佛者，宋魏二譯，皆云法佛。

Regarding the transformation Buddha (nirmāṇakāya): he merely accords with the falsely arisen views of foolish people to produce various verbal explanations and speak of particular characteristics and common characteristics, in order to make them know that dharmas are unreal. The phrase 'not the non-Buddha' (feifeifo) is translated as 'the Dharma Buddha' (dharmakāya) in both the Song and Wei translations.
