If the self is formless the soul than :-

The formless soul or consciousness, the One and Undifferentiated, which by the manifold application of its powers produces the dual and non-dual experiences (waking/dream/deep sleep) and, in the end, withdraws the three states into itself, is indeed the self—luminous.

The Maker of all the three states, self—luminous and all—pervading, Atman dwells always in the three states as its formless clay and witness. Atman is revealed by the negative way, discriminative wisdom and the Knowledge of Unity based upon reflection. The one who know the soul is the true self becomes one with the immortal self.  When there is no ignorance, there is no day or night, neither being nor none—being; the pure soul alone exists. That immutable Reality is the meaning of "the soul. From it has preceded the non-dual wisdom.

No one can grasp soul ,which is in the form of consciousness  as separate entity apart from duality because it is the formless clay and the witness of the experience of duality thus it cannot be grasped as above, across, or in the middle.

Its form is not an object of vision; no one beholds it with the eyes. They who, through pure intellect and the Knowledge of Unity based upon reflection, realize soul  as the true self becomes one with the immortal.

If the self is formless  the soul than :-

What are projection and retraction, what are end and means; what are failure and success to the formless soul, which is formless and nondual in its nature. The mirage appears and merges back into its essence is not an appearance at all.

What is the knower, the means of knowledge, the object of knowledge; what is anything or nothing to the soul which is ever formless.  Knower, knowledge, object, thing, nothing or any word one may utter is after all they are the words and words have meaning only within the mirage.  The consciousness is ever present in all the three states but as a person, one is unconscious of the consciousness because he thinks the body as his self.

When all knowing, known and knower are simultaneously mental as in dream what else is there to trouble about understanding them. Because of   considering the waking experience as reality one is incapable of understanding and assimilating the nondual truth.  

What is the distraction? What is the concentration, dullness ad delusion, happiness and sorrow to the formless soul, which is ever actionless.

As a person one may be drawn to observe his body and the world, but the Gnani is not disturbed by because they all are consciousness to him.

 The physical attributes are nothing to do with the soul/self wrongly; all the attributes belong to the ego not the soul.  Identifying the physical attribute to the soul is the cause of the ignorance.

What is relative? What is absolute happiness and misery to the formless soul, which is ever devoid of thought and activity?

If anything has a meaning it is only in duality. Happiness and sorrow are the nature of duality, which is mind, their differences therefore illusory on the standpoint of the formless soul, which is ultimate reality.  

What is illusion? What is ignorance? What are birth, life and death? What is world? What is attachment and what is detachment to the soul/self, which is ever formless. 

The mind and soul are one in essence ultimately. All argument about consciousness never touches it.  The soul is not the ego in this particular body but principle which holds the whole physical existence (universe), which contains everyone and everything known and unknown. All words have no place and thoughts cannot reach. Even the thought of the soul or consciousness is just illusory and contradictory, because the thought and words belong to the world of duality.

What is activity or inactivity, liberation and bondage to the formless soul/self, which is ever immutable and indivisible.  There is no division into nations, races and colours of kinds of men in wisdom.  It is not enough to but one must always see the formless soul (consciousness) as self and the witness the witness of all the three states and always realize and practice it.   Some people get glimpses of truth and lose it; so it must be established. Such fixidity is the goal.

What is instruction and scriptural injunction? What is disciple and guru? What indeed is object of life for the formless soul, which is absolute and free from limitation?

Life is with world. World is within the waking or dream, the illusory limitation. When there is no second other than consciousness, then what is there for the soul , the innermost self to attain? But when one thinks the self is physical, then there is various things he will want to get and so be trouble by their lack. Hence don’t wrongly imagine the self to be the body. 

What is existence, nonexistence, unity or duality? What need us there to say more? Noting from the soul because whatever seems to emanate from it, is non-different from itself.  There is no second thing other than the soul, which is in the form of consciousness. One should not mistake self (soul) for the ego.

Those who assert world is reality, are still in elementary stages of preliminary analysis. The world is reality within the waking experience but the waking experience is mere illusion. The same way the dream world was reality within the dream experience.    The dream became unreal when waking took place same way waking becomes unreal when nondual wisdom dawns.
