三修
The three ways of discipline, i.e. three rvaka and three bodhisattva ways. The three rvaka ways are 无常修 no realization of the eternal, seeing everything as transient; 非乐修 joyless, through only contemplating misery and not realizing the ultimate nirva-joy; 无我修 non-ego discipline, seeing only the perishing self and not realizing the immortal self. The bodhisattva three are the opposite of these.
