仁王經疏 3.241

3.241

釋曰：第六、變化方便。言變化者，變易異名。故《顯揚》及《唯識》依此說變易生死，名變化生。此明地上菩薩由願力故，於淨土中受變易生，不受三界分段之身，故名變化方便。

Explanation: Sixth, the expedient means of transformation. As for 'transformation' (bianhua), it is an alternative name for 'alteration' (bianyi). Therefore the *Prakaraṇāryavācā* and the *Vijñaptimātratāsiddhi*, relying on this, refer to alteration-saṃsāra as 'transformation-birth.' This explains that a bodhisattva on the stages (bhūmis), through the power of vows, takes alteration-birth in pure lands and does not take a portion-and-section body of the three realms; hence it is called the 'expedient means of transformation.'
