SB 4.7.45

brahmana ucuh
tvam kratus tvam havis tvam hutasah svayam
tvam hi mantrah samid-darbha-patrani ca
tvam sadasyartvijo dampati devata
agnihotram svadha soma ajyam pasuh
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The brahmanas said: Dear Lord, You are sacrifice personified. You are the offering of clarified butter, You are the fire, You are the chanting of Vedic hymns by which the sacrifice is conducted, You are the fuel, You are the flame, You are the kusa grass, and You are the sacrificial pots. You are the priests who perform the yajna, You are the demigods headed by Indra, and You are the sacrificial animal. Everything that is sacrificed is You or Your energy.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
In this statement Lord Visnu’s all-pervasiveness is partially explained. It is said in the Visnu Purana that as a fire situated in one place emanates its heat and illumination everywhere, so whatever we see within the material or spiritual worlds is nothing but a manifestation of different energies emanating from the Supreme Personality of Godhead. The brahmanas’ statement is that Lord Visnu is everything the fire, the offering, the clarified butter, the utensils, the place of sacrifice and the kusa. He is everything. It is confirmed herein that the performance of sankirtana-yajna in this age is as good as all other yajnas in all other ages. If one performs sankirtana-yajna by chanting Hare Krsna, Hare Krsna, Krsna Krsna, Hare Hare/ Hare Rama, Hare Rama, Rama Rama, Hare Hare, there is no need to arrange elaborate paraphernalia for the prescribed sacrificial ceremonies recommended in the Vedas. In the chant of the holy names, Hare and Krsna, Hare means the energy of Krsna, and Krsna is the visnu-tattva. Combined together they are everything. In this age, persons are harassed by the influence of Kali-yuga and cannot arrange for all the requisite paraphernalia for performing sacrifice as recommended in the Vedas. But if one simply chants Hare Krsna, it is to be understood that he is performing all kinds of yajna because there is nothing within our vision except Hare (the energy of Krsna) and Krsna. There is no difference between Krsna and His energies. Thus, since everything is a manifestation of His energy, it is to be understood that everything is Krsna. One simply has to accept everything in Krsna consciousness, and he is a liberated person. One should not misunderstand that because everything is Krsna, Krsna has no personal identity. Krsna is so full that in spite of keeping Himself separate from everything by His energy, He is everything. This is confirmed in Bhagavad-gita, Ninth Chapter. He is spread throughout the creation as everything, but still He is not everything. The philosophy recommended by Lord Caitanya is that He is simultaneously one and different.
