"Everyone has its own beauty, but not everyone sees it". Everybody is beautiful in their own unique way, for different people also have different beauty perception. What counts is the inner beauty, for the beauty inside our soul is far more important than physical beauty, since the physical beauty would not last long. What's the point of being beautiful outside when the inside is ugly? There is no need for cosmetic surgery, because we are all beautiful in our very own way, and there is no need to change our appearance, and just be the way we are. We are all the creations of God, and He create us in His image, we are all beautiful according to Him.
Look at Mother Teresa's smile, it shows the true and sincere kindness from her heart. Even in the old age, she still has her own true inner beauty that can be seen from the kindness of her face.
