維摩經玄疏 3.165

3.165

十、佛地者，大功德力資智慧，得一念相應慧，照窮真俗，一切界內習氣究竟盡也。故《智度論》云「聲聞智慧力弱，如小火燒木，雖然，猶有炭在。緣覺智慧力勝，如大火燒木，木然炭盡，餘有灰在。諸佛智慧力大，如劫燒火，炭灰俱盡」，亦如兔、馬、象三獸渡河之諭也。

Tenth, regarding the ground of the Buddha: The power of great merit supports wisdom; one attains the wisdom corresponding [to reality] in a single thought, illuminating the real and conventional to their ultimate depths, and all residual habits within the realm [of saṃsāra] are completely and definitively exhausted. Therefore the Mahāprajñāpāramitopadeśa says: 'The wisdom-power of the śrāvaka is weak, like a small fire burning wood: though burned, charcoal still remains. The wisdom-power of the pratyekabuddha is superior, like a large fire burning wood: the wood burned, the charcoal exhausted, yet ashes still remain. The wisdom-power of the buddhas is vast, like the fire that consumes an eon: charcoal and ashes are both exhausted.' It is also like the simile of the three beasts—the hare, the horse, and the elephant—crossing the river.
