The Gāthā of Chan Master Dongshan

When Dongshan took leave of Yunyan: 百年后，忽有人问，还逊得师真否，如何只对？

Yunyan was silent for a long while, then said: 只这是。

The master pondered silently.

Yunyan said: 价阇黎，承当个事，大须仔细。

The master still harbored doubts; later, upon crossing a stream and seeing his reflection, he greatly awakened to the former purport.

The verse says: 切忌从他觅，迢迢与我疏。

(Never seek true suchness outside the mind; the deluded mind is not the true mind. If one takes the deluded mind as the true mind, then every path leading to the deluded mind becomes distant from the true mind, separated by thousands of miles.)

我今独自往，处处得逢渠。

(The self of the five aggregates now walks alone by the water's edge, yet can meet Him at every place where faculty and sense-object make contact; He is everywhere.

渠今正是我，我今不是渠。

(He now is precisely the true self, yet my five aggregates are not He.)

应须恁么会，方得契如如。(One should understand it just in this way; only then can one accord with true suchness, without deviation.)
