"Do not go gentle into that good night": The speaker begins the poem with a direct and powerful command, urging the person or life force they are addressing not to submit passively to death. The phrase "good night" symbolizes death, and the speaker rejects the notion of accepting it without a struggle.
"Old age should burn and rave at close of day;/Rage, rage against the dying of the light": These lines emphasize the speaker's belief that old age and the approach of death should be met with fierce resistance. The personified "old age" is depicted as burning and raving, expressing a passionate and unrestrained response to the inevitable end of life. The repetition of "rage" and "dying of the light" reinforces the speaker's determination to fight against the fading away of life and consciousness.
"Wise men at their end know dark is right": This line suggests that wise people, as they approach the end of their lives, come to accept death as an inevitable and just part of existence. The phrase "dark is right" implies that death is inherently correct or appropriate.
"Because their words had forked no lightning they": This line provides a reason why wise men might accept death peacefully: they have not used their words to create sparks of brilliance, passion, or change.
