now become a force that binds him It gives life but also takes it away The poet then says Though I sang in my chains like the sea This is a powerful image The chains mean the limits of life and time Every human being is bound by time just as the sea is bound by its shore Yet even in these chains the poet continues to sing The sea represents eternal movement and the endless rhythm of life Through this image Dylan Thomas shows his love for life Though time has tied him down he still celebrates existence His song is his art his memory and his spirit that time cannot destroy In these lines Time becomes both jailer and teacher It binds the poet yet gives him the wisdom to sing Dylan Thomas ends the poem with beauty and strength This shows that life s song continues even within the chains of time
