The poem is built almost entirely from questions, and none of them gets an answer. It begins with simple pairs of opposites, like coming and going, or something new happening and something passing, then flips the wording back and forth until the meaning slips. That is the "confusion" of the subtitle: the speaker is turning the same few words over and finding they no longer sit still.
Then the questions grow more serious. Words like "target," "end," "path" and "way" start to link up in a chain. Does the end matter if the target changes? Is the target the reason for the way? Is the way a reason for living? The last line closes the loop with "Is life a reason for an end?", which turns the whole chain back on itself.
The mood is uneasy and searching, a bit dizzy. The speaker seems to be looking for purpose and finding only more questions. Judging by the repetition, the poem suggests that "end" can mean both a goal and a finish, and that doubt is hard to separate from the question of why we live at all.
