大般涅槃經義記 5.327

5.327

次明無緣，無緣有四：一觀五陰虛假無性；二觀五陰空寂無相，乃至因緣假名亦無；三觀五陰妄想所見，由來無法；四觀五陰體是真如，從本已來不起、不滅，而修慈心。餘亦如是，修成之義具應如此，但今文中唯就生緣以辯修相，餘略不論。

Next is clarifying [benevolence that is] objectless. The objectless has four kinds: first, contemplating the five aggregates as empty, provisional, and without own-nature; second, contemplating the five aggregates as empty, quiescent, and markless, down to conventional designations through causes and conditions also being nonexistent; third, contemplating the five aggregates as what is seen through false conceptualization, fundamentally being without dharmas; fourth, contemplating the substance of the five aggregates as tathatā, from the very beginning neither arising nor ceasing, and thus cultivating the mind of benevolence. The others are also like this. The meaning of cultivating consummation should be completely like this, but in the present text, it only distinguishes the marks of practice with reference to taking sentient beings as objects, while the others are omitted without discussion.
