Deep sleep reminds and teaches that, it is possible to have the state where there is no duality, means no birth, no life and death

Deep sleep reminds and teaches that, it is possible to have the state where there is no duality, means no birth, no life and death, no pleasure and no pain, no fear, no wants and no needs. There is no doubts and confusion, no question to answer. 

The question can be asked where the imagination is possible, that is only in illusion. Deep sleep is the second less state. The mind is at its rest and still in deep sleep. This stillness of the mind is possible only when one realizes the fact that self is neither the waking entity nor the self is dream entity but the self is the formless witness of the three states. 

Once the seeker consciously becomes aware of the existence formless witness of the three states and that formless witness is the soul or consciousness the ignorance vanishes. When the ignorance vanishes than the formless witness and the three states becomes one in essence.  When the formless witness (soul or subject) and the witnessed (mind or object) become one in essence than the mind becomes still and the duality vanishes and remains in its second less state of its existence. This realization of its second less state is freedom.
