Bhagavad Gita 4.24

ब्रह्मार्पणं ब्रह्म हविर्ब्रह्माग्नौ ब्राह्मण हुतम् |
ब्रह्मैव तेन गन्तव्यं ब्रह्मकर्मसमाधिना

Translation

For those who are completely absorbed in God-consciousness, the oblation is Brahman, the ladle with which it is offered is Brahman, the act of offering is Brahman, and the sacrificial fire is also Brahman. Such persons, who view everything as God, easily attain Him.
