妙法蓮華經玄義 7.42

7.42

If in terms of the Nirvāṇa [Sūtra], the Nirvāṇa [Sūtra] comprehensively explains the four teachings, also having thirty provisional and ten real. Superficially it seems identical to the vaipulya, yet its intent is completely different: there, two enter the real and two do not enter the real; now in the Nirvāṇa [Sūtra], all four enter the real. In the cause, there are three provisional and one real; in the fruition, there are four real and no provisional. In terms of the four siddhāntas, there are fourteen provisional and two real; traversing the four gates, fifty-six provisional and eight real; if further considered in terms of the three causal gates, fifty-six provisional; if in the fruition gate, the four real are simply real, yet because of their original causes, four are spoken of. Thus, the four gates enter the real, and in terms of fruition there are four real and twelve provisional, equal in meaning to the Lotus Sūtra.
