"Everything I write is for spiritual reasons—to help people keep their spirits up, to help transform misery into laughter or healing, to help people remember the truth of their spiritual identities. I try to shine a little light in the world, to be the light for whomever is there, whether at the market, or in a bookstore. It is my spiritual calling. I do a very meager job most of time, but this is my intention."
