摩訶止觀 5.123

5.123

天親、龍樹內鑒冷然，外適時宜，各權所據。而人師偏解，學者苟執，遂興矢石，各保一邊，大乖聖道也。若得此意，俱不可說、俱可說。若隨便宜者，應言無明法法性生一切法，如眠法法心則有一切夢事。心與緣合，則三種世間，三千相性，皆從心起。一性雖少而不無；無明雖多而不有。何者？指一為多，多非多；指多為一，一非少。故名此心為不思議境也。若解一心一切心，一切心一心，非一非一切；一陰一切陰，一切陰一陰，非一非一切；一入一切入，一切入一入，非一非一切；一界一切界，一切界一界，非一非一切；一眾生一切眾生，一切眾生一眾生，非一非一切；一國土一切國土，一切國土一國土，非一非一切；一相一切相，一切相一相，非一非一切；乃至一究竟一切究竟，一切究竟一究竟，非一非一切。遍歷一切，皆是不可思議境。

Vasubandhu and Nāgārjuna clearly reflected within and accommodated what was appropriate without, each relying on an expedient basis. Yet human masters have one-sided understandings, and learners obstinately cling, eventually unleashing arrows and stones, each defending a single side, greatly straying from the noble path. If one grasps this intent, all are unspeakable, and all are speakable. If one follows what is opportune, one should say that the factor of avidyā and dharmatā produces all phenomena, just as the factor of sleep and the mind give rise to all dream events. When the mind combines with conditions, the three kinds of worlds and the three thousand characteristics and natures all arise from the mind. The one nature, although small, is not non-existent; avidyā, although manifold, is not existent. Why? Pointing to the one as the many, the many is not many; pointing to the many as the one, the one is not small. Therefore, this mind is called the inconceivable realm. If one understands that one mind is all minds, all minds are one mind, neither one nor all; one aggregate is all aggregates, all aggregates are one aggregate, neither one nor all; one sense-base is all sense-bases, all sense-bases are one sense-base, neither one nor all; one realm is all realms, all realms are one realm, neither one nor all; one sentient being is all sentient beings, all sentient beings are one sentient being, neither one nor all; one land is all lands, all lands are one land, neither one nor all; one characteristic is all characteristics, all characteristics are one characteristic, neither one nor all; up to one ultimate is all ultimates, all ultimates are one ultimate, neither one nor all. Traversing all phenomena without exception, all are the inconceivable realm.
