The speaker imagines a future moment when they will finally take hold of their fate. Fate is pictured not as something huge or frightening but as a small songbird, held gently in steady hands. The speaker speaks to it kindly: "I see you. I accept you as you are." The final comparison is the quietest and most telling: this meeting will feel no different from speaking to oneself in a mirror. That suggests that accepting fate and accepting yourself are really the same act.
The second half brings the poem back to the present. That day is not today, and it may not be tomorrow either, though it might be. The speaker doesn't sound frustrated or impatient. Resting is treated as perfectly acceptable, and the closing line, "I stand ready," feels firm but relaxed. The mood is gentle, patient and quietly hopeful. It offers the comfort of knowing you don't have to force the big moment, only be prepared for it.
