法華玄論 4.181

4.181

答：前三種二智謂菩薩解行，即是因義，始于十信終至等覺。後常無常二智即是果位，稱妙覺地。故因果二門要具四種二智也。

Answer: The preceding three kinds of dual wisdom refer to the bodhisattva's understanding and practice, which is the meaning of the cause, beginning with the ten faiths and ending at virtual awakening. The latter two wisdoms of the permanent and impermanent are the fruit stage, called the ground of wondrous awakening. Therefore the two approaches of cause and fruit must be complete in four kinds of dual wisdom.
