Bhagavatapurana 5.19.26

5.19.26

yaiḥ śraddhayā barhiṣi bhāgaśo havir niruptam iṣṭaṃ vidhi-mantra-vastutaḥ /
ekaḥ pṛthaṅ-nāmabhir āhuto mudā gṛhṇāti pūrṇaḥ svayam āśiṣāṃ prabhuḥ //

26. (Infinitely blessed are the sons of Bharata land), for when with faith and piety, and in due shares and in the proper manner they pour offerings (into Agni) and offer them up to the gods with Mantras and according to rules, He is the One perfect Lord of all blessings, who, invoked under different names, delightfully accepts them all.
