摩訶止觀 3.207

3.207

若前三教行人，各在凡地發者，即是理發。若聞於教，是為教發。若修方便，即是觀行發。若於賢聖位中發，即是證發。此約三家入則不定也。

If practitioners of the preceding three teachings each have it burst forth on the ordinary stage, this is bursting forth through principle. If it bursts forth upon hearing the teaching, this is bursting forth through teaching. If it bursts forth upon cultivating provisional means, this is bursting forth through contemplation and practice. If it bursts forth among the stages of the worthy and noble, this is bursting forth through realization. This is indeterminateness of entry in terms of the three families.
