法華文句記 7.51

7.51

「諸經多名經王」等者，重約教釋，諸經有明法身義者，即名經王。智契於法相稱名等，故約機中對法對智名王王等，即諸部大乘與小相對，世人不了見諸大乘皆稱經王，乃謂《法華》與諸教等。今謂乳及二酥皆譚法報，雖俱稱王非諸經王，縱有經云諸經之王，不云已今當說最為第一，兼但對帶其義可知。「肆」者，放也、泄也、申也。

Regarding 'Many sūtras are named the king of sūtras', and so forth: this is re-explained in terms of the teachings. When sūtras clarify the meaning of the dharmakāya, they are named the king of sūtras. Wisdom tallying with Dharma in correspondence is called 'equal', and so forth; thus in terms of capacity, in contrast to Dharma and in contrast to wisdom, they are called 'king' and 'equal to a king', which is the various Mahāyāna sections contrasted with the Small. Worldly people do not understand, and seeing that various Mahāyāna texts are all called 'king of sūtras', they then claim that the Lotus Sūtra is equal to the other teachings. I say now: the milk and the two curds both discuss the Dharma and reward; although both are called 'king', they are not the king of all sūtras; even if a sūtra says 'king of all sūtras', it does not say that among what has been spoken, is now spoken, and will be spoken, it is the foremost; its meaning can be known through 'combined, sole, comparative, and inclusive'. 'Unrestrained' (si) means release, letting out, and expressing.
