妙法蓮華經玄義 2.160

2.160

圓入別二諦者，俗與別同，真諦則異。別人謂：不空但理而已；欲顯此理，須緣修方便，故言「一切法趣不空」。圓人聞不空理，即知具一切佛法無有缺減，故言「一切趣不空」也。約此，亦有隨情等（云云）。

As for the two truths of the perfect entering the distinctive: the conventional is the same as the distinctive, but the ultimate truth differs. A person of the distinctive considers: the non-empty is merely principle alone; to reveal this principle, one must rely on conditional cultivation of expedients, hence it is said that 'all dharmas converge upon the non-empty'. A person of the perfect, hearing the principle of the non-empty, immediately knows that it is endowed with all buddha-dharmas without deficiency, hence it is said that 'all converge upon the non-empty'. With respect to this, there are also [the meanings of] according with sentiment, and so on.
