In fact, the truth of Zen is the truth of life, and life means to live, to move, to act; not merely to reflect.
Zen professes itself to be the spirit of Buddhism, but in fact it is the spirit of all religions and philosophies. When Zen is thoroughly understood, absolute peace of mind is attained, and a man lives as he ought to live. What more may we hope?
The basic idea of Zen is to come in touch with the inner workings of our being, and to do this in the most direct way possible, without resorting to anything external or superadded. Therefore, anything that has the semblance of an external authority is rejected by Zen. Absolute faith is placed in a man's own inner being. For whatever authority there is in Zen, all comes from within.
