Dust

"Better was it to go unknown and leave behind you an arch, then to burn like a meteor and leave no dust."

"Faith. Trust. and Pixie Dust."

"Yet how hard most people work for mere dust and ashes and care, taking no thought of growing in knowledge and grace, never having time to get in sight of their own ignorance."

"We come spinning out of nothingness, scattering stars like dust."
