分別功德論 3.8

3.8

念休息者，謂得定也。休息有二：有俗休息、有道休息。俗休息者，猶行作疲極，小住懈息，故名為俗休息。道休息者，謂定之人。何以知其然？昔有比丘名曰等會，時近大道邊坐禪定意。時有五百乘車過，聲甚凶凶，寂然不聞。時復天雷霹靂，又頃復地大動，都無所聞。行過者眾，塵土坌衣，積有時節。有一人來，見此比丘端坐不動，塵土坌衣都無所覺耶？比丘定覺，抖擻塵土。又問曰：「向者眠耶？」曰：「不也。」又問：「若不眠者，向有車過及天雷地動。寂然不驚，何由如此？」答曰：「我時入休息三昧，是以都無所聞耳。」以是言之，得休息定者，雖復天地覆墜不革其志，故名休息定也。

Mindfulness of resting (upaśama) refers to attaining concentration. Resting is of two kinds: worldly resting and resting in the path. Worldly resting is like being exhausted from walking and working, and pausing briefly to rest; hence it is called worldly resting. Resting in the path refers to a person of meditative concentration. How is this known to be so? Formerly there was a monk named Samāgama, who sat in meditation to concentrate his mind near a great highway. At that time, five hundred carts passed by with an immense clamour, yet in stillness he heard nothing. Then thunder crashed and lightning struck, and shortly after the earth shook violently, yet he heard nothing at all. Many travellers passed by, dust settling upon his robes and accumulating over time. A person came and, seeing this monk sitting upright and motionless, asked, 'With dust settling upon your robes, were you completely unaware?' The monk awoke from his concentration and shook off the dust. [The person] asked, 'Were you asleep just now?' He said, 'No.' [The person] asked again, 'If you were not asleep, just now carts passed by, thunder struck, and the earth shook. In stillness you were not startled; what was the reason for this?' He replied, 'At that time I had entered the samādhi of resting; therefore I heard nothing at all.' From this it is said: when one attains the concentration of resting, even if heaven and earth overturn and collapse, it does not alter one's resolve; hence it is called the concentration of resting.
