A person, who stamped his foot on the ground to refute to show the world, is real, ignore that in dream he would do exactly the same--stamp his dream foot on the ground and assert it to be real.+

The dream becomes unreal when waking takes place. That means the dream entity, people within the dream and the dream world becomeS unreal. In the same way, the waking entity and people within the waking experience and the waking world become unreal when wisdom dawns. 

A person, who stamped his foot on the ground to refute to show the world, is real, ignores that in the dream he would do exactly the same--stamp his dream foot on the ground and assert it to be real. 

From the standpoint of the waking entity, the universe is a reality from the standpoint of the Soul, the Self, the universe is merely an illusion created out of consciousness. When wisdom dawns then one realizes the whole universe is consciousness. The dualistic view is possible only in ignorance. 

At the dawn of Self-knowledge or Brahma Gnana or Atma Gnana, there is only the non-dualistic view in the midst of duality because the whole universe is consciousness. Thus all the contents of the universe are also consciousness.  Form, time, and space are merely an illusion created out of consciousness. If the form, time, and space are consciousness then the experience of birth, life, and death is also consciousness.    

Advaitic Sage and Maya or illusion  

VlSHNUVARDHANA, the King of the Hoysalas, was a Vaishnavite and was greatly incensed at the doctrine taught by Advaitic Sage that everything here below is an illusion. He wanted to teach the exponent of this doctrine a lesson. So he invited the then Advaitic Sage to his palace. That holy man went there and stoutly maintained that everything in this world was an illusion. The king had arranged to let loose an infuriated elephant against Advaitic Sage. The beast rushed at Advaitic Sage who took to a precipitate flight to save himself.

'Oh, Venerable Sir,' shouted the king, 'why do you run so fast seeing that the elephant is only an illusion?'

'Oh, king,' said  Advaitic Sage in the course of his flight, 'my running too is an illusion. Everything in this world is an illusion.’ 

Similarly, we are unaware of the fact that we are within the illusion because we exist within the waking world.  The waking experience itself is an illusion.  Due to ignorance of the Soul, the Self, the illusion is experienced as reality. 

All our love and concern for humanity is a reality within the illusion.:~Santthosh Kumaar
