You need to spend time crawling alone through shadows to truly appreciate what it is to stand in the sun.
Each time a person passes by you and you say 'hello', imagine that person turning into a candle. The more positivity, love and light you reflect, the more light is mirrored your way. Sharing beautiful hellos is the quickest way to earn spiritual brownie points. You should start seeing hellos as small declarations of faith. Every time you say hello to a stranger, your heart acknowledges over and over again that we are all family.
I have not yet lost a feeling of wonder, and of delight, that this delicate motion should reside in all the things around us, revealing itself only to him who looks for it. I remember, in the winter of our first experiments, just seven years ago, looking on snow with new eyes. There the snow lay around my doorstep — great heaps of protons quietly precessing in the earth's magnetic field. To see the world for a moment as something rich and strange is the private reward of many a discovery.
