Something that reflects comes back to you. If you look in a mirror, you will see your reflected image. If you reflect on your past experiences, you look at them once again thoughtfully.
Reflect also means to give evidence of the character or quality of something. Most parents want their children to reflect their own strengths by emulating their behavior. A set of telling statistics could reflect the buying trends in an economic cycle. Reflecting can mean seeing something original in another form or image.
