Śrāddha-Kalpa: Pitṛ-Pūjā and Tithi-Phala (श्राद्धकल्पः पितृपूजा च तिथिफलम्)
तत् समाप्य यथोटद्विष्ट॑ पूर्वकर्म समाहित: । दातुं निर्वप्णं सम्यग् यथावदहमारभम्,एकाग्रचित्त होकर शास्त्रोक्तविधिसे पिण्डदानके पहलेके सब कार्य समाप्त करके मैंने विधिवत् पिण्डदान देना आरम्भ किया
tat samāpya yathokta-dviṣṭa-pūrvakarma samāhitaḥ | dātuṃ nirvapṇaṃ samyag yathāvad aham ārabham ||
ഏകാഗ്രചിത്തനായി ശാസ്ത്രവിധിപ്രകാരം പിണ്ഡദാനത്തിന് മുമ്പുള്ള എല്ലാ മുൻകർമ്മങ്ങളും പൂർത്തിയാക്കി, തുടർന്ന് ഞാൻ യഥാവിധി നിർവപണം—അഥവാ പിണ്ഡദാനം—ആരംഭിച്ചു।

The verse emphasizes disciplined adherence to śāstric procedure: one should complete the prescribed preliminaries with mental composure, and only then perform the main act of giving (here, the piṇḍa/oblation). Ethical action is framed as careful, rule-guided, and mindful.
Bhīṣma describes his own performance of a śrāddha-related rite: after finishing the required preliminary actions, he begins the proper offering of the nirvapṇa (ritual oblation/piṇḍa) in the correct manner.
