一雲，二風塵，三煙，四阿修倫。即日月蝕。以譬貪瞋痴慢之煩惱。
The four films, or things that becloud, i. e. rain-clouds; dust-storms; smoke; and asuras, i. e. eclipses of sun and moon; emblematic of desire, hate, ignorance, and pride; cf. 四結.
一四翳 即以雲、風塵、煙、日月蝕等四種能障蔽吾人視野之自然現象來比喻貪、瞋、癡、慢等四種煩惱。蓋眾生之貪、瞋等煩惱能障蔽真如本性，猶如雲、煙等之遮掩視野，故稱四翳。p2363
