Aśauca-vidhi (Rules of Impurity) within Śrāddha-kalpa — Chapter on Testing/Selecting Brahmanas and Honoring the Atithi
पुष्पमूलफलैर्वापि तुष्टा गच्छेयुरन्ततः / यावन्न श्रपितं चान्नं यावतौष्ण्यं न मुञ्चति
puṣpamūlaphalairvāpi tuṣṭā gaccheyurantataḥ / yāvanna śrapitaṃ cānnaṃ yāvatauṣṇyaṃ na muñcati
即使以花、根与果供养,诸祖灵(Pitṛ)终亦满足而去——只要熟食尚未失其温热。
