[f94] According to this, there must have been a special volume of sermons and letters by Hui-k‘ê, which were compiled evidently by his disciples and admirers before they were put down in writing and thoroughly revised by the author himself. In the case of Bodhi-Dharma too, according to Tao-hsüan, his sayings were apparently in circulation in the day of Tao-hsüan, that is, early in the T‘ang dynasty. [f95] Understood by some to be leprosy. [f96] In the _Vimalakīrti_, Chapter III., “The Disciples,” we have the following: “Do not worry about the sins you have committed, O monks,” said Vimalakīrti, “Why? Because sins are in their essence neither within nor without nor in the middle. As the Buddha taught us, all things are defiled when Mind is defiled; all things are pure when Mind is pure: and Mind is neither within nor without nor in the middle. As is Mind, so are sins and defilements, so are all things—they never transcend the suchness of truth.” [f97] _Hsin_, is one of those Chinese words which defy translation. When the Indian scholars were trying to translate the Buddhist Sanskrit works into Chinese, they discovered that there were five classes of Sanskrit terms which could not be satisfactorily rendered into Chinese. We thus find in the Chinese Tripitaka such words as _prajñā_, _bodhi_, _buddha_, _nirvāṇa_, _dhyāna_, _bodhisattva_, etc., almost always untranslated; and they now appear in their original form among the technical Buddhist terminology. If we could leave _hsin_ with all its nuance of meaning in this translation, it would save us from the many difficulties that face us in its English rendering. For _hsin_ means mind, heart, soul, spirit—each singly as well as all inclusively. In the present composition by the third patriarch of Zen, it has sometimes an intellectual connotation but at other times it can properly be done by “heart.” But as the predominant note of Zen Buddhism is more intellectual than anything else, though not in the sense of being logical or philosophical, I decided here to translate _hsin_ by “mind” rather than by “heart.” [f98] This means: When the absolute oneness of things is not properly understood, negation as well as affirmation will tend to be one-sided view of reality. When Buddhists deny the reality of an objective world, they do not mean that they believe in the unconditioned emptiness of things; they know that there is something real which cannot be done away with. When they uphold the doctrine of void this does not mean that all is nothing but an empty hollow, which leads to a self-contradiction. The philosophy of Zen avoids the error of one-sidedness involved in realism as well as in idealism. [f99] I.e., Tat tvam asi. [f100] There is however a variation from five years to fifteen years according to different authorities.
