Chapter 1: The Practice of the Knowledge of all Modes — While at Vulture Peak, the Buddha asks Subhūti to explain how bodhisattvas realise the Prajñāpāramitā. Subhūti explains that when disciples of the Buddha who realise dharmatā teach, that is the work of the Buddha. He goes on to clarify the realisation of the Perfection of Wisdom by explaining that by cutting off the view of the inherent existence of self and phenomena, a bodhisattva can go forth on the Mahāyāna for the liberation of beings and not enter nirvāṇa halfway. However, in suchness, he points out, there are in fact no bodhisattvas, beings to save, Prajñāpāramitā, path, or nirvāṇa.
