चक्षुर्वै ग्रहः स रूपेणातिग्राहेण गृ-हीतश्चक्षुषा हि रूपाणि पश्यति ॥ ५ ॥
In plain words
The eye is a grasper — seized by form itself, its own over-grasper. Because it is through the eye that we see the shapes of things.
Close to the Sanskrit
The eye, indeed, is a grasper; it is seized by form as the over-grasper; for by the eye one sees forms.
