। ॥ ४१२ ॥
In plain words
Skin is made from a portion of air, so what it takes hold of is touch — air's own quality. The eye is made from a portion of fire, so what it takes hold of is form and colour — fire's own quality.
Close to the Sanskrit
The skin, by being a portion of air, grasps touch, the quality of that. The eye, by being a portion of fire, grasps form, the quality of that.
