2.118

第一、入禪調三事者，行人欲入三昧，調身之宜，若在定外，行住進止，動靜運為，悉須詳審。若所作麁獷，則氣息隨麁。以氣麁故，則心散難錄。兼復坐時煩憒，心不恬怡，是以雖在定外，亦須用心逆作方便。

First, harmonizing the three matters upon entering dhyāna: when the practitioner wishes to enter samādhi, regarding the propriety of harmonizing the body, while outside of concentration, in walking, standing, moving, and stopping, in every movement, rest, and activity, all must be measured and deliberate. If what one does is coarse and rough, the breath will become coarse accordingly. Because the breath is coarse, the mind will be scattered and difficult to collect. In addition, when sitting, one will be agitated and confused, with the mind lacking tranquility. Therefore, even though outside of concentration, one must mindfully take preparatory expedients in advance.
