The idea took hold of me. It was a little like being shown a door in a familiar room — the room of your own mind — that you had somehow never noticed before and being told by people you trusted (scientists!) that a whole other way of thinking — of being! — lay waiting on the other side. All you had to do was turn the knob and enter. Who wouldn’t be curious? I might not have been looking to change my life, but the idea of learning something new about it, and of shining a fresh light on this old world, began to occupy my thoughts. Maybe there was something missing from my life, something I just hadn’t named.
