Visuddhimagga VIII-192

Tassa evaṃ gaṇayato nikkhamantā ca pavisantā ca assāsapassāsā pākaṭā honti.

如是数出与数入的（瑜伽）者，便得明了出息和入息；

Ñ(VIII,192): As he does his counting in this way, the in-breaths and out-breaths become evident to him as they enter in and issue out.

Athānena taṃ dandhagaṇanaṃ dhaññamāpakagaṇanaṃ pahāya sīghagaṇanāya gopālakagaṇanāya gaṇetabbaṃ.

于是那时，他得放弃像量谷者之数的慢慢地数，而取如牧牛者的数的快快地数。

Ñ: Then he can leave off counting slowly (late), like a grain measurer, and he can count quickly [that is, early] as a cowherd does.

Cheko hi gopālako sakkharādayo ucchaṅgena gahetvā rajjudaṇḍahattho pātova vajaṃ gantvā gāvo piṭṭhiyaṃ paharitvā palighatthambhamatthake nisinno dvārappattaṃ dvārappattaṃyeva gāviṃ ekā dveti sakkharaṃ khipitvā gaṇeti.

即熟练的牧牛者，取些小石子放在衣角内，手拿绳与鞭，早晨前往牛舍，打了牛的背，坐在门栏的柱头上，对于从（牛舍的）门口出来每头牛，都「一、二」的投以石子而数。

Ñ: For a skilled cowherd takes pebbles in his pocket and goes to the cow pen in the morning, whip in hand; sitting on the bar of the gate, prodding the cows in the back, he counts each one as it reaches the gate, saying 'One, two', dropping a pebble for each.

Tiyāmarattiṃ sambādhe okāse dukkhaṃ vutthagogaṇo nikkhamanto nikkhamanto aññamaññaṃ upanighaṃsanto vegena vegena puñjapuñjo hutvā nikkhamati.

因为在三时的（初中后）一夜苦居于迫窄的空间内的牛群，（从牛舍）出来时，互相拥挤，急速地一群一群的出来。

Ñ: And the cows of the herd, which have been spending the three watches of the night uncomfortably in the cramped space, come out quickly in parties, jostling each other as they escape.

So vegena vegena ‘‘tīṇi cattāri pañca dasā’’ti gaṇetiyeva,

他便「三、四、五」乃至「十」而急速地数。

Ñ: So he counts quickly (early) 'Three, four, five' and so up to ten.

evamimassāpi purimanayena gaṇayato assāsapassāsā pākaṭā hutvā sīghaṃ sīghaṃ punappunaṃ sañcaranti.

如是此（瑜伽）者亦用以上（急速）的方法来数，他对出息入息既得明了，便快快地数数而行。

Ñ: In this way the in-breaths and out-breaths, which had already become evident to him while he counted them in the former way, now keep moving along quickly.
