This is a very interesting try-mind story. It means, from moment to moment only “do it.” Only keep a try mind, only one mind: do it mind. When chanting, sitting or bowing, only do it. Practicing will not help if you are attached to your thinking, if your mind is moving. Taoist chanting, Confucian chanting, Christian chanting, Buddhist chanting: it doesn’t matter. Even chanting, “Coca Cola, Coca Cola, Coca Cola…” can be just as good if you keep a clear mind. But, if you don’t keep a clear mind, even Buddha cannot help you. The most important thing is, only do it. When you only do something one hundred percent, then there is no subject, no object. There’s no inside or outside. Inside and outside are already one. That means you and the whole universe are one and never separate.
