‘Truth is truth. There are not two truths, only one. When you understand truth only with your mind, you may feel that is the truth. But compared to your actual activity or feeling or life, the truth that you understand with your mind is not the actual truth. Because our actual life is not as easy as our thinking, it is easy to be convinced that some idea we have is the perfect truth. Yet for us it is not true because that kind of thinking does not accord with our actual life.’ (Branching Streams flow in the Darkness)
I left the previous quote short to emphasise his basic point, but the way Suzuki Roshi expands on that reveals the depth of his understanding.
