ब्रह्मादिस्थावरान्तेषु वैराग्यं विषयेष्वनु ।यथैव काकविष्ठायां वैराग्यं तद्धि निर्मलम् ॥ ४ ॥
In plain words
From Brahmā at the top to a stone at the bottom: turn away from all of it exactly the way you turn away from crow droppings. That turning away is the spotless kind.
Close to the Sanskrit
Dispassion with regard to objects, from Brahmā at the beginning to immovable things at the end — just exactly as there is dispassion toward crow's excrement — that indeed is spotless.
