The appropriation of Karma-pudgalas (material clusters qua Karma) through special effort, when the bondage of the Āyuṣya (life-span-determining) Karma occurs.
ākarṣo nāma tathāvidhena prayatnena karmapudgalopādānam.
(PrajnāVṛ Pa 218)
jīvā ṇaṃ bhaṃte! jātiṇāmaṇihattāuyaṃ katihiṃ āgarisehiṃ pakareṃti? goyamā! Jahāṇṇeṇaṃ ekeṇa vā dohiṃ vā tihiṃ vā, ukkoseṇaṃ aṭṭhahiṃ.
(Prajñā 6.120)
