第三、初入定調心者。調心有二義：一者、調伏亂念，不令越逸；二者、當令沈浮寬急得所。何等為沈相？若坐時心中昏暗，無所記錄，頭好低垂，是為沈相。爾時當繫念鼻端，令心住在緣中，無令散意，此可治沈。何等為浮相？若坐時心神飄動，身亦不安，念在異緣，此是浮相。爾時宜安心向下係緣，制諸亂念，心則定住，此則心易安靜。舉要言之，不沈不浮，是心調相。

Third, as for regulating the mind upon initial entry into concentration: regulating the mind has two aspects: first, subduing disordered thoughts so that they do not run wild; second, ensuring that sinking, floating, laxity, and tenseness are properly balanced. What is the mark of sinking? If while sitting the mind is dim and dark, recollecting nothing, and the head tends to droop, this is the mark of sinking. At that time, one should tie mindfulness to the tip of the nose, keeping the mind abiding in the object of focus without letting thoughts scatter; this can remedy sinking. What is the mark of floating? If while sitting the mental spirit is fluttering and restless, the body is also unsettled, and thoughts dwell on extraneous objects, this is the mark of floating. At that time, it is fitting to settle the mind downward and tie it to a lower focus, checking the scattered thoughts so that the mind comes to a halt; through this the mind easily becomes peaceful and tranquil. To state the essential point: being neither sunken nor floating is the mark of a regulated mind.
