Dvinnaṃ pana samādhīnaṃ idaṃ nānākāraṇaṃ, upacāre aṅgāni na thāmajātāni honti, aṅgānaṃ athāmajātattā, yathā nāma daharo kumārako ukkhipitvā ṭhapiyamāno punappunaṃ bhūmiyaṃ patati, evameva upacāre uppanne cittaṃ kālena nimittamārammaṇaṃ karoti, kālena bhavaṅgamotarati.

It is because they are not strong that when access has arisen, the mind now makes the sign its object and now re-enters the life-continuum, just as when a young child is lifted up and stood on its feet, it repeatedly falls down on the ground.
Appanāyaṃ pana aṅgāni thāmajātāni honti, tesaṃ thāmajātattā, yathā nāma balavā puriso āsanā vuṭṭhāya divasampi tiṭṭheyya, evameva appanāsamādhimhi uppanne cittaṃ sakiṃ bhavaṅgavāraṃ chinditvā kevalampi rattiṃ kevalampi divasaṃ tiṭṭhati, kusalajavanapaṭipāṭivaseneva pavattatīti.
