三修

The three ways of discipline, i.e. three śrāvaka and three bodhisattva ways. The three śrāvaka ways are 無常修 no realization of the eternal, seeing everything as transient; 非樂修 joyless, through only contemplating misery and not realizing the ultimate nirvāṇa-joy; 無我修 non-ego discipline, seeing only the perishing self and not realizing the immortal self. The bodhisattva three are the opposite of these.
