If there is a meaning in life at all, then there must be a meaning in suffering. Suffering is an ineradicable part of life, even as fate and death. Without suffering and death, human life cannot be complete.
~ Viktor E. Frankl
When you take a dirty floor ... and make it spotlessly clean, and this polish it until it shines, it radiates back to you the love which you poured into it; the divinity of that floor has been drawn forth.
