AbstractHuman beings have never been satisfied with this ephemeral world. Perhaps, yearning and desire of rejoining −stemming from the descent from the heaven to the earth− are the emotions felt by the members of both celestial and non-celestial religions. Mysticism, having started with the zeal of people who weren‘t satisfied with this ephemeral world towards the eternal world, aimed at the love of God in the religions where there is a belief of single God. In this article, glancing at the life of a Christian mystic William Blake, we will try to shed light into his mystic thoughts. While studying Blake‘s mystic thoughts, there will be common points with Sufism. Nevertheless, analysis of these common points has been assigned to other studies.
