As long as a person clings to the belief in causality, the experience of duality will prevail as reality. But when this attachment to causality wears away, the duality becomes non-existent as reality.
The three states are created by false knowledge; therefore nothing in it is eternal. Everything, again, as one with Ultimate Reality, is unborn; therefore there is no such thing as destruction.
Birth is ascribed to the individual; but such birth is not possible from the standpoint of Reality. Their birth, life and death are part of the illusion. That illusion, again, does not exist. The illusory sprout is born of the illusory seed. This illusory sprout is neither permanent nor destructible. The same applies to the individual and the world.
The term permanent or impermanent cannot be applied to the birthless self. What is indescribable in words cannot be discriminated about as permanent or impermanent.
As in dreams the mind acts through illusion, presenting the appearance of duality, so also in the waking state the mind acts through illusion, presenting the appearance of duality. There is no doubt that the mind, which is in reality non-dual, appears to be dual in dreams; likewise, there is no doubt that what is non-dual i.e. consciousness , appears to be dual in the waking experince.
