"Looked at, it cannot be seen; it is called colorless. Listened to, it cannot be heard; it is called soundless. Grasped, it cannot be obtained; it is called formless. These three cannot be investigated further, so they merge together to make one.* The upper part is not bright; The lower part is not dark. So subtle, it cannot be named, But returns to nothingness. This is called the shape without shape, the image without image.** This is called indistinct:*3* confronting it, one cannot see the head; following it, one cannot see the back. Grasp the Ancient Tao to manage present existence.*3* Thus we may know the beginning of the Ancient. This is called the record*4* of Tao.*5*"
