Crossing the Bar

This poem contains two major metaphors for death. They both represent death. The first one is going out to sea and him crossing the sandbar. The second one is the sunset and evening star (night) representing death. I noticed that it was talking about death when it mentioned the pilot and sleep. I thought the pilot was God and that sleep was death. Also, when it said "one clear call for me," it sounded like he was being called home to heaven. The speaker is ready to die and to move on to the after life. "May there be no sadness in my farewill", he is telling his family and friends to not be sad when he moves on to better things because it is not sad, it is a happy time.
