Until, the breath of this corporeal frame
And even the motion of our human blood
Almost suspended, we are laid asleep
In body, and become a living soul:
While with an eye made quiet by the power
Of harmony, and the deep power of joy,
We see into the life of things. I would say that this passage of this poem perhaps hints of immortality about becoming "a living soul" and "seeing into the life of things" suggesting that a living soul can never die and what we see in the life of things is something which never dies as long as there is organic life.
Explanation:
A petrochemical is any chemical manufactured from crude oil and natural gas as distinct from fuels and other products (Speight, 2014, 2019a), derived from crude oil and natural gas, and used for a variety of commercial purposes. The definition has been broadened to include the whole range of organic chemicals.
