About

A public-domain repository of Zen kōan in the original Chinese with free English translations.

Zen kōan come down to us mostly in Classical Chinese, in collections composed eight or nine centuries ago. Those original texts are unambiguously in the public domain. Most good English translations, however, are still under copyright. This project pairs the public-domain originals with new translations that are themselves freely usable — so the whole thing, original and translation alike, belongs to everyone.

The three parts of each entry

Original — the public-domain classical Chinese text, set in our own punctuation. The wording is the ancient text itself, checked character by character, not any modern edition.

Translation — faithful but readable: accurate to the Chinese, in natural modern English, with a light touch of bracketed glossing only where a term truly needs it.

Pointer — a curator's note. Not an interpretation that resolves the kōan (that would defeat its purpose) but an oblique nudge: the cultural and doctrinal context a monk in the original audience already carried, and which a modern reader usually lacks.
