四明十義書 2.73

2.73

若謂爾者，宴謂僻解，非是圓談。須知觀妄心成真心，即是觀妄心成如來也。若觀妄成觀行真，名造觀行如來。若觀妄成相似真，名造相似如來。分證、究竟，例之可知（六即如來，故云諸也）。

If you assert this, I declare it to be an erroneous understanding and not a perfect discourse. You must understand that contemplating the deluded mind to accomplish the true mind is precisely contemplating the deluded mind to accomplish the Tathāgata. If contemplating the deluded accomplishes the true of contemplative practice, this is called producing the Tathāgata of contemplative practice. If contemplating the deluded accomplishes the true of resemblance, this is called producing the Tathāgata of resemblance. For partial realization and ultimate [realization], you may infer by analogy (referring to the Tathāgatas of the six identities, hence the word "various").
