Educational Q&A
The core teaching is that steadfast completion of prescribed religious disciplines (here, ‘four āvartanas’) generates vast puṇya, whose reward is portrayed as lasting across immense cosmic time-measures—highlighting the Mahābhārata’s link between disciplined dharma-practice and enduring karmic results.
Bhīṣma is instructing (as a dharma-teacher figure) about the spiritual efficacy of a particular observance: he states that a person who completes the four cycles of that practice enjoys its meritorious fruit for extraordinarily long periods, expressed through grand cosmological units (lotus-years, mahākalpas, caturyugas).
