Illusions are mistakes in perception. The earth is not actually flat but it looks that way; the woman in the magic trick is not actually being sawed in half, it just looks that way. When we understand the underlying circumstances, then the illusion dissolves. It may still appear (the earth still looks flat) but now we know what is true. Separation is an illusion that is healed by understanding the way in which we are not – and cannot ever be – separate from creation and creator.
