Have you reckon'd a thousand acres much?

From Section 2 of Song of Myself:

Have you reckon'd a thousand acres much? have you reckon'd the earth much?
Have you practis'd so long to learn to read?
Have you felt so proud to get at the meaning of poems?

Stop this day and night with me and you shall possess the origin of all poems,
You shall possess the good of the earth and sun, (there are millions of suns left,)
You shall no longer take things at second or third hand, nor look
through the eyes of the dead, nor feed on the spectres in books,
You shall not look through my eyes either, nor take things from me,
You shall listen to all sides and filter them from your self.

This section of the poem, directed to the reader, promises
that spending time with the poet will open the reader's eyes, 
will help get at truth.
