Sūtra on the Great Collection of Dharma Teachings 1.78

1.78

「復次，四顛倒，是佛所說。謂無常謂常，是故生起想顛倒、心顛倒、見顛倒。以苦謂樂，是故生起想、心、見倒。無我謂我，是故生起想、心、見倒。不淨謂淨，是故生起想、心、見倒。如是等名為四顛倒。

"Furthermore, four viparyāsas were spoken by the Buddha: taking the impermanent to be permanent, whereby there arise viparyāsa of perception, viparyāsa of mind, and viparyāsa of view; taking what is suffering to be happiness, whereby there arise viparyāsa of perception, of mind, and of view; taking what is non-self to be self, whereby there arise viparyāsa of perception, of mind, and of view; taking the impure to be pure, whereby there arise viparyāsa of perception, of mind, and of view. These are called the four viparyāsas.
