After Long Silence

This poem by Yeats was kind of hard to understand. It talks about love and death and love after death. Silence is the only symbol that this poem has, so you know that you only have 1 theme. This line puzzled me: Speech after long silence; it is right,. But then it goes on and it gets confusing talking about lovers. It seems like when you are quiet or say things quiet but with intensity it has more of an affect on the person.
