摩訶止觀 9.105

9.105

答：《華嚴》云：「一中無量；無量中一。」《大品》云：「一切法趣無明，是趣不過；乃至一切法趣老死。」今說一心具十二因緣，當有何咎？復次，言一念，不同世人取著一異定相一念，乃是非一非異而論一耳。譬如泯法覆心，一念之中夢無量世，事如《法華》（云云）。

Answer: The Avataṃsaka Sūtra says: 'Within the one is the immeasurable; within the immeasurable is the one.' The Pañcaviṃśatisāhasrikā Prajñāpāramitā Sūtra says: 'All phenomena converge into ignorance, and this convergence cannot be exceeded; up to all phenomena converging into old age and death.' Now in speaking of a single mind being complete with the twelve links of dependent origination, what fault could there be? Furthermore, speaking of a single thought-moment is not like worldly people clinging to a fixed characteristic of unity or diversity in a single thought-moment; it is discussing oneness in terms of neither-one-nor-different. For example, when mental phenomena submerge and envelop the mind, within a single thought-moment one dreams of immeasurable lifetimes, as described in the Lotus Sūtra (and so forth).
