妙法蓮華經玄義 8.161

8.161

菩薩須知，如此心起，即是六道苦集，名為塞；如是心起，即是二乘道滅，名為通。又如是心起是二乘苦集，名為塞；如是心起是菩薩道滅，名為通。如是心起，名為菩薩苦集；如是心起，名佛道滅。於苦集中，能知非道，通達佛道；能知佛道，起於壅塞，了了無滯，是為識通塞。

The bodhisattva must know: when such a mind arises, it is the suffering and origin of the six destinies, and is termed 'obstructed'; when such a mind arises, it is the path and cessation of the two vehicles, and is termed 'open.' Furthermore, when such a mind arises, it is the suffering and origin of the two vehicles, and is termed 'obstructed'; when such a mind arises, it is the path and cessation of the bodhisattva, and is termed 'open.' When such a mind arises, it is termed the suffering and origin of the bodhisattva; when such a mind arises, it is termed the path and cessation of the Buddha. Within suffering and origin, one is able to know what is not the path and penetrate the Buddha path; one is able to know that the Buddha path can give rise to blockages, yet remain completely unobstructed—this is knowing the open and the obstructed.
