"I awake with a not entirely sickened knowledge that I am merely young again and in a funny way at peace, an observer who is aware of time's chariot, aware that some metamorphosis has occurred"

This quote talks to the idea of getting older and the changes that come with it. The speaker is reviewing the truth that they are no longer young, but that they are at peace with this fact. They are aware of the passage of time and the modifications that include it, and they accept them. The speaker is also mindful that something has actually altered within them, which they have actually gone through some type of improvement. This change is not always a bad thing, as the speaker is not "sickened" by it. Rather, they are at peace with the changes that include age, and they are content to observe the passage of time.
