A thing of beauty is a joy forever: its loveliness increases; it will never pass into nothingness. – John Keats… And I would venture farther and say if the beauty comes from within then it truly will not ever fade.

It is really not so difficult to be beautiful; or rather feel beautiful; because the creator has created us in his likeness so all of us are beautiful. All that you need to see and experience beauty within yourself and in others is to connect with the goodness inside you!
I do believe that everything around us; our world is a reflection of that which is happening inside us. Inside our mind inside our soul! Why is it that when we are in a good mood the morning is bright and sunny and the birds are chirping? Why is it that when we are sad all the songs on the radio are melancholy? How many times you have been thinking of someone and that someone either calls or meets you?
The sooner we realize that the beauty we are looking for in the mirror will come only when we show the mirror our beauty! After all it is only a mirror! Experiment this; think a sad thought and look in the mirror and then after a few seconds remember a happy moment and then look in the mirror. Notice something?
