Abstract
William Blake belongs to one of those visionary artists who, during his lifetime, did not receive much recognition from society, was not understood and therefore even marked as “crazy”, his art “odd”. Nevertheless, a small circle of sensitive connoisseurs favored and supported him. But fortunately, his work was not completely forgotten. It seems that today William Blake is being highly valued. An extensive exhibition of his fine, masterful artwork was shown at Tate Britain in London till February 2020. His pictorial, sensitive works are of inestimable value to us today as they address areas that are so important for the further development of mankind nowadays. For William Blake, imprisonment of a human being does not mean only the physical, as a slave, but above all the spiritual, the mental. Unfortunately, mental slavery is not recognized as such by mankind, as Blake let us know, this is influence of sly forces. From early childhood he had visions of God and angels. For him it was clear and undoubted that man should be innocent as a small child and therefore is under God’s protection. However, according circumstances emanating from negative forces, man is enthralled and drowned in it. Keywords: religion, mental slavery, mental freedom, love for mankind, salvation
