"Dr. Abraham Maslow opened the way to a new look at mental health. He studied several persons whom he saw as self-actualizing and fully human. What he reported about their "peak experiences" rang uncannily like the reports of the mystics. Here at last was someone trying to establish a model of the healthy psyche, and included in it, almost like a stamp of authenticity, was the mystical experience!"
