Just because we can't see the Soul, it doesn’t mean it doesn't exist, although this is a common way in which people deny the existence of the Soul, which is present in the form of consciousness.  

People think the Soul does not exist because their master says so or some teaching says so or some scriptures say so.  First, they must know the fact that the Soul is not an individual, but is universal. 

The Soul, which is present in the form of consciousness pervades the whole universe as its formless substance. 

The Soul is One without a Second 

The Soul is Self-evident.  It is not established by extraneous proofs. It is not possible to deny the Soul, because It is the very essence of the one who denies It. The Soul is the basis of all kinds of knowledge, presuppositions, and proofs.  

The Soul is hidden by the 'I', the Soul is without the 'I'.The Soul is the cause of the 'I'. The Soul itself is uncaused. 

The whole universe in which you exist is nothing but the Soul, which is present in the form of consciousness. Thus, the Soul alone is real and the universe is merely an illusion created out of the Soul.

 The Soul is not an object, as it is invisible, beyond the reach of the physical eyes. Hence, the Upanishads declare: “Neti Neti—not this, not this....” This does not mean that the Soul, which is present in the form of consciousness, is a negative concept or a metaphysical abstraction, a nonentity, or a void. 

It is not another. It is all-full, infinite, changeless, Self-existent, Self-delight, Self-knowledge, and Self-awareness.  The Soul is the essence. It is the substance and witness of the three states, which come and go.

 If God is apart from the Soul, the innermost Self, then He would be Self-less, that is, outside existence, that is, non-existent. 

The mind (universe) and its substance and its source (Soul) are one, in essence.  That essence is consciousness. Consciousness alone is real all else is merely an illusion created out of consciousness. Consciousness is the ultimate Truth or Brahman. The ultimate truth is God in truth.  

The Soul or consciousness appears as the diverse universe is only an illusion. If it really became diverse then the immortal would become mortal. 

The dualist’s thinkers who seek to prove the origination of the unborn, by that very enterprise try to make the immortal, mortal.  

The ultimate nature can never change - the immortal can never become mortal and vice versa. "There's no plurality in the nature of the Soul." Consciousness appears to be many”; "those who are attached to creation or production or origination are in ignorance because their approach is more practical, and they are stuck with the reality of the universe (waking) and take it as real.

The dualist thinkers ’ arguments are based on false Self (ego you) and false experience (mind or waking or dream or universe)    to show the weakness of the position of the dualistic viewpoint.  They are at their wits end to explain. :~Santthosh Kumaar
