David Spero is a spiritual teacher and author. He lives in California. While in college he meditated intensely and experienced spiritual raptures and samadhis, culminating in nirvikalpa samadhi in 1980. Sixteen years later, while he was sitting in a motel room, his meditation descended into unfathomable depths, and his "I" and the world dissolved forever in an ocean of divine light. Describing this experience, he writes, "I was, without question, That, and in the most profound sense, That alone. I had come home."
