The expression ‘Brahman is the instrument to offer with’1 is adjectival to ‘the oblation”. That by which an offering is given, such as a ladle, is an Arpana. It is called Brahman because it is an effect of Brahman , Brahman being the material cause of the universe. ‘Brahmaarpanam’ is the oblation, of which the instrument is Brahman. The oblation, just like the instrument with which it is offered, is also Brahman. It is offered by the agent Brahman into the fire of Brahman. He is the Brahma-karma-samadhi who contemplates thus on all acts as filled with the Supreme Brahman or as having the Supreme Brahman as the Self. He who contemplates on Brahman as the Soul of all actions, reaches Brahman alone, as his own self has the Supreme Brahman as Its Self. The meaning is that the individual self—which is Brahman because of Its having Brahman as Its Self—has to realise Its own real nature. All actions performed by an aspirant for release have the form of knowledge because of their association with the contemplation of the Supreme Brahman as their self. They are a direct means for the vision of the self without the meditation of Jñana Yoga.

Thus, Shri Krishna, after explaining how Karma takes the form of knowledge, now speaks of the various kinds of Karma Yoga.
