修習止觀坐禪法要 1.62

1.62

夫初欲入禪調身者，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。身雖在定外，亦須用意逆作方便，後入禪時，須善安身得所。

When first wishing to enter dhyāna and harmonize the body: for a practitioner wishing to enter samādhi, the suitability of harmonizing the body—when outside concentration, in walking, standing, moving, and halting, in activity, rest, and action—must in all respects be examined with care. If what one does is coarse and rough, the breathing will accordingly be coarse. Because the breath is coarse, the mind will be scattered and difficult to collect; in addition, during sitting one will be vexed and troubled, and the mind will not be serene and joyful. Even when the body is outside concentration, one must carefully apply expedient means in advance; thereafter, upon entering dhyāna, one must properly position the body in its proper place.
