The expression 'Brahma-arpanam' (Brahman is the instrument) is an adjectival to 'Brahma-havih' (Brahman is the oblation). That, by which an offering is made, such as a ladle, is an arpana — it is called Brahman because it is an effect of Brahman and Brahman is the material cause of the universe. 'Brahma-arpanam' therefore refers to the instrument of the oblation which is Brahman. The oblation, just like the instrument with which it is offered, is also Brahman. It is offered by the agent who is Brahman into the fire of Brahman. One who is thus mindful of all acts being permeated by the Supreme Brahman or in other words as having the Supreme Brahman as its ground is the Brahma-karma-samadhi. One who contemplates on Brahman as the ground of all actions reaches Brahman alone — because his own Self has the Supreme Brahman as its (Over)-Self.
