The concentration, however, may not be kept up to such an almost abnormal degree as in the case of Bukko. It may last just a second or two, and if it is the right kind of concentration and rightly handled by the master, the inevitable opening of the mind will follow. When the monk Jō (Ting) asked Rinzai,[5.42] “What is the ultimate principle of Buddhism?” the master came right down from his seat, took hold of the monk, slapped him with his hand, and pushed him away from him. The monk stood stupefied. A bystander suggested, “Why don’t you make a bow?” Obeying the order, Jō was about to bow when he abruptly awoke to the truth of Zen. In this case Jo’s self-absorption or concentration did not seemingly last very long, the bowing was the turning point, it broke up the spell and restored him to sense, not to an ordinary sense of awareness, but to the inward consciousness of his own being. Generally we have no records of the inner working prior to a satori, and may pass lightly over the event as a merely happy incident or some intellectual trick having no deeper background. When we read such records, we have to supply from our own experience, whatever this is, all the necessary antecedent conditions for breaking up into a satori. IX So far the phenomenon called satori in Zen Buddhism has been treated as constituting the essence of Zen, as the turning point in one’s life which opens the mind to a wider and deeper world, as something to be gleaned even from a most trivial incident of everyday life; and then it was explained how satori is to come out of one’s inner life, and not by any outside help except as merely indicating the way to it. Next I proceeded to describe what a change satori brings in one’s idea of things, that is, how it all upsets the former valuation of things generally, making one stand now entirely on a different footing. For illustrations, some verses were quoted which were composed by the masters at the moment of their attainment of satori. They are mostly descriptive of the feelings they experienced,, such as those by Bukko and Yōdainen and Yengo and others are typical of this class, as they have almost no intellectual elements in them. If one tries to pick up something from these verses by a mere analytical process, one will be greatly disappointed. The psychological side of satori which is minutely narrated by Hakuin and others will be of great interest to those who are desirous of making a psychological inquiry into Zen. Of course these narratives alone will not do, for there are many other things one has to consider in order to study it thoroughly, among which I may mention the general Buddhist attitude towards life and the world and the historical atmosphere in which the students of Zen find themselves. I wish to close this Essay by making a few general remarks in the way of recapitulation on the Buddhist experience known as satori.
