The speaker kicks the poem off by bragging about the scope of human imagination. Of course, she does it all poetically by talking about how much wider the brain is than the sky. She goes on to talk about the human brain's amazing ability to absorb information by saying that the brain is deeper than the sea. Last, she declares that our amazing brains give us god-like powers and tries to prove her theory with the following equation: the brain = the weight of God. Guess this lady really has a thing for the brain.
