Mahabharata — Anushasana Parva, Shloka 13
अत्रेः तपोबलप्रकाशः तथा च्यवनस्य सोमाधिकारः
Atri’s Illumination by Tapas; Cyavana and Soma-Entitlement
न च संध्यामुपासीत न च जाप्य॑ प्रवर्तयेत् । न संकिरेत् तदन्नं च ततः पूर्येत ब्राह्मण:
na ca sandhyām upāsīta na ca jāpyam pravartayet | na saṅkīret tad-annaṃ ca tataḥ pūryeta brāhmaṇaḥ ||
Wika ni Bhīṣma: “Sa araw na ang isang brāhmaṇa ay kumain ng pagkaing inihandog sa śrāddha, hindi niya dapat isagawa ang pagsamba sa sandhyā, hindi niya dapat simulan ang pagbigkas ng japa (gaya ng Gāyatrī), at hindi rin siya dapat kumain muli. Sa pagsunod sa mga pagpipigil na ito, ang ritwal na kalinisan ng brāhmaṇa ay naibabalik at napapanatili nang wasto.”

Educational Q&A
A brāhmaṇa who eats the śrāddha meal should observe specific restraints that day—refraining from sandhyā worship, from initiating mantra-japa (e.g., Gāyatrī), and from eating again—so that ritual purity and propriety connected with the śrāddha are preserved.
In the Anuśāsana Parva’s instruction on dharma, Bhīṣma is laying down detailed rules of conduct related to śrāddha observances, specifying what a brāhmaṇa participant should avoid on the day he partakes of the śrāddha offering.
