肇論新疏 1.203

1.203

是以聖人乘真心而理順，則無滯而不通；審一氣以觀化，故所遇而順適。

Therefore, the sage mounts the true mind so that principles are in accord, and thus there is nowhere he is obstructed and fails to penetrate; he examines the single vital breath to observe transformations, and therefore whatever he encounters is harmonious and fitting.
