法華玄論 1.30

1.30

問：心無所得乃是偏空義耳。《大經》呵云「汝等勿謂如來唯修諸法本性空寂」，故知空者空耳，蓋是二乘所見。又《大品》、三論可得明空，《法華》開權顯實，《涅槃》明常住佛性，何得明空？將非田夫啞鹽、舊醫用乳？

Question: The mind having nothing to attain is merely the meaning of biased emptiness. The Great Sūtra rebukes this, saying, 'Do not say that the Tathāgata only cultivates the original nature of all dharmas as empty and quiet.' Hence we know that emptiness is merely empty, which is what the two vehicles see. Furthermore, the Pañcaviṃśatisāhasrikā and the Three Treatises may illuminate emptiness, but the Lotus Sūtra opens the provisional to reveal the real, and the Nirvāṇa Sūtra illuminates the eternal Buddha-nature; how could they illuminate emptiness? Would this not be like the rustic mute with salt, or the ancient physician prescribing milk?
