四明十義書 1.36

1.36

又撰《五義書》云：觀心之義有三種，唯止觀約行觀心，乃立陰等為境，揀示識心以為所觀。若附法、託事二種觀心，但是直附事相、法相，觀之攝事成理，皆不立陰入為境。乃至云：請搜撿一家教義，還有託事附法觀別立陰入為境否？脫或有之，必希垂示。

He then composed the *Letter on Five Points*, saying: 'The meaning of contemplating the mind is of three kinds: only the contemplation of the mind in terms of practice in Zhiguan establishes the aggregates, etc., as the object, selecting and pointing out the conscious mind as the object of contemplation. In the two kinds of contemplation of the mind that append to teachings and entrust to phenomena, one merely appends directly to phenomenal marks and doctrinal marks, and contemplating them gathers phenomena into principle; neither establishes the aggregates and sense bases as the object.' He even said: 'Please search the teachings and doctrines of our school: is there any contemplation of entrusting to phenomena and appending to teachings that separately establishes the aggregates and sense bases as the object? If perchance there is, I truly hope you will point it out.'
