The poem is LONG, so chances are good that you can find similarities to anything. But, I thought these were pretty cool.
"A child said, What is the grass? fetching it to me with full hands;
How could I answer the child? I do not know what it is, any more than he.
I guess it must be the flag of my disposition, out of hopeful green stuff woven."

"They are alive and well somewhere;
The smallest sprout shows there is really no death;
And if ever there was, it led forward life, and does not wait at the end to arrest it,
And ceas’d the moment life appear’d.
All goes onward and outward—nothing collapses;
And to die is different from what any one supposed, and luckier."

"I ascend from the moon, I ascend from the night;
I perceive that the ghastly glimmer is noonday sunbeams reflected;
And debouch to the steady and central from the offspring great or small."
