The Commentary states: Among the three natures, it is the paratantra-svabhāva. In speaking of the objective condition (ālambana-pratyaya), it must be an existing dharma; parikalpita cittas, etc., take this as their condition, because the immediate nimittabhāga must be paratantra. They do not take the pariniṣpanna as their object, because it is not similar to it. Fascicle 4 of the Mahāyānasaṃgraha states exclusively that the paratantra-svabhāva is that which is parikalpita.
