ब्रह्मार्पणं ब्रह्म हविर्ब्रह्माग्नौ ब्रह्मणाहुतम् ।
ब्रह्मैव तेन गन्तव्यं ब्रह्म कर्म समाधिना ।।
Brahmarpanam Brahma Havir
Brahmagnau Brahmana Hutam
Brahmaiva Tena Ghantavyam
Brahmakarma Samadhina
The act of offering is Brahman, the oblation is Brahman,
By Brahman it is offered into the fire of Brahman.
Brahman is That which is to be attained by s/he
who performs actions pertaining to Brahman.
