天台八教大意 1.46

1.46

Further, citing the *Nirvāṇa Sūtra* to confirm and establish its principle, the sixth fascicle states: 'An ordinary person is like milk; a srotaāpanna is like curd; a sakṛdāgāmin is like fresh butter; an anāgāmin is like clarified butter; and an arhat, pratyekabuddha, and buddha are like ghee.' The *Mahāprajñāpāramitopadeśa* (*Dālun*) states: 'In the śrāvaka sūtras, an arhat is called the buddha-ground; therefore the three persons are equally ghee.' This metaphor corresponds to the five flavors of the Tripiṭaka teaching.
