成具光明定意經云。何謂廣一心。曰。孝事父母則一其心。尊敬師友而一其心。斷愛遠俗而一其心。入三十七品而一其心。空閑寂寞而一其心。在眾煩亂而一其心。多欲多諍多作多惱。於是之處而一其心。褒訕利失善惡之事。於是不搖而一其心。數息入禪。捨六就淨而一其心。身自能行。復教他人。此謂廣一心也。

The Chengju guangming dingyi jing states: "What is called expanding the one mind? It is said: filial service to parents makes one's mind one. Respecting teachers and friends makes one's mind one. Cutting off attachment and distancing oneself from worldliness makes one's mind one. Entering the thirty-seven factors [of enlightenment] makes one's mind one. Being in empty leisure and quiet loneliness makes one's mind one. Being among the multitude in confusion and distraction makes one's mind one. Where there is much desire, much contention, much activity, and much distress, making one's mind one in such places. Regarding praise and blame, gain and loss, good and bad affairs, remaining unshakeable in these and making one's mind one. Counting breaths and entering dhyāna, abandoning the six [sense objects] to approach purity, and making one's mind one. Personally being able to practice this, and moreover teaching others—this is called expanding the one mind."
