“Mirrors should reflect before sending an image.”

“Mirrors should think longer before they reflect.”

“You are right not to meet my glance, my lord, for then I see into your heart too clearly. It is a mirror which retains the image which it has reflected.”

“The eyes are the mirror of the soul and reflect everything that seems to be hidden; and like a mirror, they also reflect the person looking into them.”

“The One true God may be compared unto the sun and the believer unto a mirror. No sooner is the mirror placed before the sun than it reflects its light. The unbeliever may be likened unto a stone. No matter how long it is exposed to the sunshine, it cannot reflect the sun.”

“No matter how long you stand there examining yourself naked before a mirror, you'll never see reflected what's inside.”

“It's a good idea to carry a small mirror in your pocket, which will give you a reflection of yourself before you judge others.”

“History and the past should be a mirror for us to reflect on our own ugliness, shortcomings and depravity. Not just to preen and beautify ourselves.”

“If intellection and knowledge were mere passion from without, or the bare reception of extraneous and adventitious forms, then no reason could be given at all why a mirror or looking-glass should not understand; whereas it cannot so much as sensibly perceive those images which it receives and reflects to us.”

“When you wish to see whether the general effect of your picture corresponds with that of the object represented after nature, take a mirror and set it so that it reflects the actual thing, and then compare the reflection with your picture, and consider carefully whether the subject of the two images is in conformity with both, studying especially the mirror. The mirror ought to be taken as a guide… you see the picture made upon one plane showing things which appear in relief, and the mirror upon one plane does the same. The picture is on one single surface, and the mirror is the same. …if you but know well how to compose your picture it will also seem a natural thing seen in a great mirror.”
