妙法蓮華經玄義 1.113

1.113

心如幻焰，但有名字，名之為心。適言其有，不見色質；適言其無，復起慮想。不可以有、無思度故，故名心為「妙」。妙心可軌，稱之為「法」。心法非因、非果，能如理觀，即辦因果，是名「蓮華」。由一心成觀，亦轉教餘心，名之為「經」。釋名竟。

The mind is like an illusory flame, existing only as a name; it is named 'mind'. Just when one says it exists, no physical form is seen; just when one says it is non-existent, deliberate thoughts arise again. Because it cannot be conceived in terms of existence or non-existence, the mind is called 'wondrous'. The wondrous mind can serve as a model, and is termed 'Dharma'. The mental dharma is neither cause nor fruit; being able to contemplate it in accordance with principle immediately accomplishes cause and fruit, which is named 'lotus blossom'. Through the one mind accomplishing contemplation, it also transforms and teaches other minds; this is named 'sūtra'. This concludes explaining the title.
