If waking experience is mere illusion than the individual experience of birth, life, death and the world , which takes place within the waking experience is mere illusion.

It is important to remember that emptiness here does not refer to nothingness but to the nature of the soul, the innermost self. 

Buddhism says:-  all things are illusory and nothing exists.  However, Advaita avers that it is not so.  It says that the universe of course is illusory, but there is Brahman, that exists forming the very substratum of all things. 

Seeker of truth read not to contradict and confute, nor to believe and take for granted, nor to find talk and discourse, but to weigh and consider and discover the truth by using his own reason.  The greatest and noblest pleasure which seeker can have is to discover new truths; and drop old prejudices and accumulated knowledge.

To understand and assimilate Self-knowledge or Brahma Gnana or Atma Gnana   one must speak from the standpoint of the  soul or consciousness. Humility, intense urge of inner growth is necessary in pursuit of truth.  

Emptiness refers to the fact that,  the truth is empty of untruth  or  duality. Describing this non-dual experience in words is not really possible, as language is based on duality and contrasts. Trying to explain this experience - which contradicts our normal perception - is a bit like explaining colors to someone who is born blind; difficult to say the least. But the serious seeker can grasp it mentally. 

All obstacles are due to identifying ‘I’ as  self.  The deeper self -search  reveals the fact that,  neither   the self is   the waking entity nor the self is the  dream entity but the self is the formless soul , which witnesses the coming and going of the three states. Therefore, it is necessary for seeker to investigate and verify the facts about the ‘I’ to realize that, the ‘I’ is not the self, but ‘I’ is mind.  The mind is in the form of the universe. 

The universe appears as waking or dream and disappears as deep sleep.  The individual experiences of birth, life, death and the world are within the waking experience.  The dream is a parallel waking experience and waking is parallel dream.

Deeper self-search reveals the fact that the, self is neither the waking entity nor the self is the dream entity but the self is formless soul, which witnesses the coming and going of the three states in succession without the physical apparatus.  This has to be mentally grasped and assimilated to realize the formless soul, the innermost   self is nothing to do with the three states. On the standpoint of the three states, the three states are mere illusion.

The practical life within the practical world, which is present as waking experience, is mere illusion. If waking experience is mere illusion than the individual experience of birth, life, death and the world , which takes place within the waking experience is  mere illusion.   If the experience birth, life death and the world are mere illusion, it means the form; time and space are mere illusion.  If form, time and space are mere illusion, it means the past, present and future is mere illusion. Thus it is necessary for the seeker to realize the fact that,   form, time and space are one in essence, in order to realize the three states are one in essence. That essence is consciousness. Thus all the diversity is created out of   formless consciousness. Thus no second thing exists other than consciousness, the innermost self. Seeker of truth has to constantly reflect on the subject in order to get a firm conviction of the truth.  The seeker has to reflect on the same truth again and again until it becomes reality. One needs to constant reflect on the subject until he gets a firm conviction of what is what.

Words are needed until one gets a firm conviction of ‘what is what. People need to read and hear the words to think deeply and reach the ultimate end.   Formless Path blogs and Inner Path blogs help the seeker to remove the mental blockade, which is blocking his realization. And it also helps to dispel the all the inborn and inherited conditioning or samskara from the subconscious.

 FP and IP blogs will help  not only as information to move in the right direction to reach the ultimate end of understanding but also helps as subconscious suggestions, which is very much necessary to establish in non-dual reality.  By repeated reading and reflecting FP and IP blogs helps the seeker. FP and IP blogs are not teaching or theory. It only helps the seeker to remove the all the obstacle in the path of truth and reach the ultimate end in lesser time and effort.
