"There was a door to which I found no key: There was the veil through which I might not see"

This quote by Omar Khayyam talks to the idea of the unidentified and the unknowable. It recommends that there are some things in life that are beyond our understanding and control. The door and veil represent the borders of our understanding and experience. We may look for the secret to unlock the door, however it might never ever be discovered. Likewise, we may strive to see beyond the veil, but it may stay forever out of reach. This quote serves as a suggestion that there are some things in life that are merely beyond our understanding. It encourages us to accept the limitations of our knowledge and to be content with the secrets of life.
