Generally speaking, we are accustomed to a way of dualistic thoughts. For instance, we usually say opposite things together using antithesis like a ‘day and night, life and death, being and non-being, love and hate, heaven and hell’ and so on. It’s no problem to divide those things into the opposite sides. But the opposite elements can be perceived as oneness from the unified view. William Blake said that ‘Without contraries is no progression’ as well. As all of us know, water and fire have an antipathy to each other. But we must have both water and fire in order to lead our life. And we cannot live without going toward death. What is more, every object cannot exist without extinguishing itself. Therefore those things are called oneness in Buddhism. William Blake also insisted that we can realize the whole world as one family by dint of the creative imagination. He regards Jesus as a ‘Poetic Genius’. Because the poetic genius (as we now call it) has the creative imagination. Blake was a Christian, but there is a common ground between his thought and the middle path of Buddhism. If we think over The Marriage of Heaven and Hell, the title of his poetry, we can agree easily that the opposite worlds are really one cosmic family.
