Our deepest fear is not that we are inadequate. Our deepest fear is that we are powerful beyond measure. It is our light, not our darkness That most frightens us. We ask ourselves, "Who am I to be brilliant, gorgeous, talented, fabulous?" Actually, who are you not to be? You are a child of God. Your playing small does not serve the world. There's nothing enlightened about shrinking so that other people won't feel insecure around you.
We are all meant to shine, as children do. We were born to make manifest the glory of God that is within us. It's not just in some of us; It's in everyone. And as we let our own light shine, we unconsciously give other people permission to do the same. As we're liberated from our own fear, our presence automatically liberates others.
-- Marianne Williamson
Philosophy is written in that great book which ever is before our eyes -- I mean the universe -- but we cannot understand it if we do not first learn the language and grasp the symbols in which it is written. The book is written in mathematical language, and the symbols are triangles, circles and other geometrical figures, without whose help it is impossible to comprehend a single word of it; without which one wanders in vain through a dark labyrinth.
-- Galileo Galilei
