In English
It may be argued that even the physical eyes help to acquire knowledge. The eyes see everything but cannot see themselves. Eyes which cannot see themselves, how can they see the mind or see (the Divine Lord)? To have a vision of the Lord, the physical eyes are not competent. One must acquire the eyes of wisdom for this purpose. The eyes are there, but when they develop a disease the eyes are not aware of it. When the ears lose the power of hearing, they are not aware of the loss. The senses which cannot know their own state, how can they know God? The physical eyes can only serve to see external objects in Nature and examine their properties and explain them, but cannot recognize the Divine.
