仁王經疏 3.245

3.245

Explanation: Second, showing expedient wisdom. 'Skillfully functioning' generally marks the four functionings. That is, the four functionings of the subsequent wisdom of that bhūmi are subtle and skillful; hence they are called 'skillfully functioning.' 'Not realizing' and so forth specifically shows the four functionings. 'Not realizing' means unlike non-Buddhists who realize the four dhyānas and consider them nirvāṇa. 'Not sinking' means unlike ordinary beings who sink in saṃsāra. 'Not emerging' means unlike the two vehicles who emerge from saṃsāra. 'Not arriving' means unlike bodhisattvas prior to the bhūmis who have not arrived at the first bhūmi. Or perhaps 'not arriving' is an error and should read 'not inverted,' meaning that bodhisattvas prior to the bhūmis still give rise to inversions, and to distinguish from them it says 'not inverted.' 'Is the contemplation of expedient means' concludes that the four functionings above are all subsequent wisdom.
