妙法蓮華經文句 2.34

2.34

約教者，自有滅色空智生，體色空智生，從有智生空智，從空智生俗智，從俗智生中智，空生即有智，是圓空智生，而今是圓空智生也。

In terms of the teachings: there is the birth of the wisdom of emptiness through the annihilation of form; the birth of the wisdom of emptiness through realizing the nature of form; the birth of the wisdom of emptiness from wisdom of existence; the birth of conventional wisdom from the wisdom of emptiness; the birth of middle wisdom from conventional wisdom; and that empty birth is itself wisdom of existence, which is the birth of perfect wisdom of emptiness—and here it is the birth of perfect wisdom of emptiness.
