In this poem by Kabir, he speaks about a land where there is no doubt or sorrow. He even says so explicitly in the second verse:
(...)"There is a land where no doubt nor sorrow have
rule:
where the terror of Death is no more."(...)
<u>This poem is a metaphor of heaven, God, and an angel or soul</u> (ancient and timeless) <em>represented by the swan.</em> The speaker wants to know where the soul goes when one dies, what it wants, what's the purpose of life. There is a connection to God that brings the soul joy and happiness. It also makes it feel sure about the existence of God and existing forever.
