四明十義書 1.89

1.89

上人今立非染非淨之真心為能造，染淨諸法為所造，意以能造所造俱為所觀之境便謂深得止觀之意。乃錯認之甚也。

Venerable Sir, you now establish the true mind that is neither defiled nor pure as that which is capable of producing, and the defiled and pure dharmas as that which is produced, intending that both what is capable of producing and what is produced be the contemplated object, and thereby claiming to have deeply grasped the intent of Zhiguan. This is indeed a profound misconception.
