妙法蓮華經文句 4.78

4.78

四、約觀心釋者，觀於心性三諦之理不可思議，此觀明淨，名為開；雖不可思議，而能分別空、假、中心，宛然無濫，名為示；空、假、中心，即三而一、即一而三，名為悟；空、假、中心，非空、假、中，而齊照空、假、中，名為入。是為一心三觀而分開示悟入之殊也。

Fourth, in terms of contemplation of mind: contemplating the principle of the three truths of mind-nature as inconceivable—this contemplation being bright and pure is called 'opening.' Though it is inconceivable, it can distinguish the mind of emptiness, provisionality, and the middle distinctly without confusion—this is called 'demonstrating.' The mind of emptiness, provisionality, and the middle being three yet one, one yet three, is called 'awakening to.' The mind of emptiness, provisionality, and the middle being neither emptiness, provisionality, nor the middle, yet illuminating emptiness, provisionality, and the middle equally, is called 'entering.' This is how the single mind and three contemplations are differentiated into the distinctions of opening, demonstrating, awakening to, and entering.
