Explanation:
Emerson means that he sees everything; the metaphor suggests the poet is like a single, huge eye. I become a transparent eyeball; I am nothing; I see all; the currents of the Universal Being circulate through me; I am part or parcel of God.

Hope this helps! :)
Hello. You did not provide the text to which this question refers, which makes it impossible to answer it exactly, but I will try to help you in the best possible way.
The word "absolutely" means something complete that is presented in its entirety in an integral way. Another meaning that this word has is the sense of independence. Something absolute is something that does not need to relate to anything, nor depend on anything for what it is.
