二十五、福田。荊溪云：經動者，釋有進退。初以四禪皆名無動，次第四禪及以四空乃名無動。此但他人所解。今明如上所明無動但屬於福，皆是有漏，故皆屬動。對理無漏，方名不動。

Twenty-five: Field of Merit. Jingxi says: "Regarding 'movement' in the sūtra, the explanations have variations. First, taking the four dhyānas as all being named 'unmoved'; next, taking the fourth dhyāna and the four formless [attainments] as being named 'unmoved.' These are merely the explanations of others. Now it is clarified that the 'unmoved' explained above merely belongs to merit; all are tainted, and therefore all belong to movement. Only in contrast to the untainted principle is it called 'unmoving.'"
