In this case, as in other cases, the idea of the masters is to show the way where the truth of Zen is to be experienced, but not in and through the language which they use and which we all use, as the means of communicating ideas. Language, in case they resort to words, serves as an expression of feelings or moods or inner states, but not of ideas, and therefore it becomes entirely incomprehensible when we search its meaning in the words of the masters as embodying ideas. Of course, words are not to be altogether disregarded inasmuch as they correspond to the feelings or experiences. To know this is more important in the understanding of Zen. Language is then with the Zen masters a kind of exclamation or ejaculation as directly coming out of their inner spiritual experience. No meaning is to be sought in the expression itself, but within ourselves, in our own minds, which are awakened to the same experience. Therefore, when we understand the language of the Zen masters, it is the understanding of ourselves and not the sense of the language which reflects ideas and not the experienced feelings themselves. Thus it is impossible to make those understand Zen who have not had any Zen experience yet, just as it is impossible for the people to realise the sweetness of honey who have never tasted it before. With such people, “sweet” honey will ever remain as an idea altogether devoid of sense, that is, the word has no life with them. Goso Hōyen first studied the Yogācāra school of Buddhist philosophy and came across the following passage: “When the Bodhisattva enters on the path of knowledge, he finds that the discriminating intellect is identified with Reason, and that the objective world is fused with Intelligence, and there is no distinction to be made between the knowing and the known.” The anti-Yogācārians refuted this statement, saying that if the knowing is not distinguished from the known, how is knowledge at all possible? The Yogācārians could not answer this criticism, when Hsüan-chang who was at the time in India interposed and saved his brethren in faith from the quandary. His answer was: “It is like drinking water, one knows by oneself whether it is cold or not.” When Goso read this, he questioned himself, “What is this that makes one know thus by oneself?” This was the way he started on his Zen tour, for his Yogācāra friends being philosophers could not enlighten him, and he finally came to a Zen master for instruction.
