। ॥ २० ॥
In plain words
Phlegm from his nose, phlegm from his mouth, waste from below — he lets it all out and is revolted by the sight of it. The same thing is spread right through his insides, and that he never notices.
Close to the Sanskrit
Discharging phlegm from the tip of the nose or from the mouth, and filth from the anus, he himself comes to disgust; and he does not know what has spread within.
