The inner eye can fill life with light or darkness.

²²The light of the body is the eye: if therefore thine eye be single, thy whole body shall be full of light.

²³But if thine eye be evil, thy whole body shall be full of darkness. If therefore the light that is in thee be darkness, how great is that darkness!

³⁴The light of the body is the eye: therefore when thine eye is single, thy whole body also is full of light; but when thine eye is evil, thy body also is full of darkness.

³⁵Take heed therefore that the light which is in thee be not darkness.

³⁶If thy whole body therefore be full of light, having no part dark, the whole shall be full of light, as when the bright shining of a candle doth give thee light.
