Duality is the world of Nature. Duality is illusory on the standpoint of the soul and it is reality on the standpoint of the physical Self/Ego. Mind is soul itself in one form. The individual experiences or temporal involvement within the mind, bound to be illusory. because the mind itself is myth.
The separation from soul on account of physical self/ego makes the soul forget its original, true, non-dual nature. Three states are a product of the soul’ and sustained by the soul, and finally dissolves as the soul’.
On account of ignorance of its true nature, it puts itself in wrong relations with other and with the objective universe. It creates a web of its own and gets itself entangled in it. This is an illusion, because the web has no reality. Thus all the three states are mere myth on the standpoint of the soul, which is the true self.
This waking, the world of false relations created by the soul, is illusory. Illusion rises from the soul and it is not apart from the soul. The illusion is independent reality witnessed by the “Soul/Self”. The “Self /Soul” is within the illusion as the formless substance, and it is apart from the illusion as its formless witness. Thus, the body and its experience of the world also is illusory because the waking itself is illusory.
