तपोधनो! मनुष्य जिस प्रकार बिना किसी संशयके यज्ञका फल पाता है, वह सब पूर्णरूपसे बताऊँगा, सुनो ।।
Bhīṣma uvāca: Tapodhana! manuṣyaḥ yathā vinā saṁśayena yajñasya phalaṁ prāpnoti, tat sarvaṁ pūrṇarūpeṇa vakṣyāmi—śṛṇu. Pauṣamāsasya śukle vai yadā yujyeta Rohiṇī, tena nakṣatrayogena ākāśaśayano bhavet.
तपोधनाः! यथा मनुष्यः संशयरहितो यज्ञफलं लभते तत् सर्वं निखिलेन वक्ष्यामि, शृणुत। पौषमासस्य शुक्ले यदा रोहिणी नक्षत्रयोगेन युज्येत, तदा तस्यां रात्रौ आकाशशयनो भवेत्॥

Educational Q&A
Bhishma teaches that disciplined observances aligned with sacred time—performed with purity, faith, and concentration—can yield merit comparable to major sacrifices, showing that inner sincerity and right practice can substitute for costly ritual.
In Anuśāsana Parva, Bhishma continues instructing on dharma and religious observances; here he prescribes a specific time-bound vow in the month of Pauṣa when Rohiṇī is conjoined, stating that sleeping under the open sky on that night grants great sacrificial merit.
