"I never saw a wild thing sorry for itself."
In the above lines, D.H Lawrence states that he has never seen an animal feel sorry for itself. These lines convey to the readers of the poem that humans often dwell on their misfortunes and pity themselves, whereas an animal accepts the misfortunes and keeps moving forward in life. One should be like these animals, not paying attention to their misfortunes, but rather moving on in life.
"A small bird will drop frozen dead from a bough without ever having felt sorry for itself."
The above quote is from the last line in this short poem. Through the above lines, the poet conveys to the readers that an animal as small as a bird is not afraid of death. A bird might just die while sitting on a tree branch. However, it does not fear death. He uses the above lines to motivate the readers, explaining to them that they shouldn't be afraid of death and live their life to the fullest without thinking about the inevitable death.
