The Brain is wider than the Sky — Burden of God

Each Brain in the three quatrains is used differently to fit its own description: brain-work of painting, brain coral, and the powerful human brain. Traditional analysis cannot fulfill every line, like Blue to Blue, Pound for Pound.

Can "the weight of God" be measured? The first two quatrains are used to support the third, Dickinson's view on God.

The Brain－is wider than the Sky－¹
For－put them side by side－
The one the other will contain
With ease－and You－beside－

The Brain is deeper than the sea－⁵
For－hold them－Blue to Blue－
The one the other will absorb－
As Sponges－Buckets－do－

The Brain is just the weight of God－⁹
For－Heft them－Pound for Pound－
And they will differ－if they do－
As Syllable from Sound－

The promulgator who had given birth to the idea was eminently essential to give it progress by still further brain-work. . . . The term called "copyright" having been since applied legally to books, designs, music, paintings, sculpture, and other original mental productions, ─ The Fortnightly (1865)
