पुण्यपापविनाशान्ते पुण्यपापसमीरित: । देहं विशति कालेन ततो<यं कर्मसम्भवम्
puṇyapāpavināśānte puṇyapāpasamīritaḥ | dehaṁ viśati kālena tato 'yaṁ karmasambhavam ||
অসিত বললেন—পুণ্য ও পাপের ফল ক্ষয়প্রাপ্ত হলে, সেই পুণ্য-পাপেরই প্রেরণায় জীব যথাকালে দেহে প্রবেশ করে; অতএব এই দেহধারণ নিজের কর্মজাত।

Embodiment is governed by moral causality: when the stored results of merit and sin reach their completion, the jīva is driven by those karmic forces to take up another body; thus worldly existence is karma-born.
In Śānti Parva’s instruction on dharma and liberation, the sage Asita explains the mechanism of rebirth: the exhaustion and momentum of puṇya and pāpa determine the next entry into a body over time.
