Satori is samadhi and yet not samadhi. It is a glimpse, and a glimpse in the very ordinary of the extraordinary: samadhi happening in ordinary moments. A sudden thing also — it is not gradual, you don’t move in degrees. It is just like water coming to boiling point, to one hundred degrees — and then the jump, and the water becomes vapor, merges into the sky, and you cannot trace where it has gone. Up to ninety-nine degrees it is boiling and boiling and boiling, but not evaporating. From the ninety-ninth degree it can fall back, it was only hot. But if it passes the hundredth degree, then there is a sudden jump.
