There is no purpose of life because the Self’ is not you, but the ‘Self’ is the Soul, which is birthless and deathless.+

From the non-dualistic perspective, there is no purpose in life because the Self’ is not you but the ‘Self’ is the Soul, which is birthless and deathless because the ‘Self’ is the ever formless, timeless, and spaceless existence whereas you are bound by the birth, lie, death, and the world.

If the ‘Self' is not you then the world in which you exist is bound to be an illusion. If the world in which you exist is bound to be an illusion then the purpose of life is a reality only within the dualistic illusion. There is no purpose of any sort because there is no second thing that exists other than the Soul, which is present in the form of consciousness. then the world in which you exist is bound to be an illusion.

f the world in which you exist is bound to be an illusion then the purpose of life is a reality only within the dualistic illusion. There is no purpose of any sort because there is no second thing that exists other than the Soul, which is present in the form of consciousness.

Only on the dualistic perspective, there is a purpose of life because the experience of birth, life, death, and the world is considered as reality. But the duality is merely an illusion from the non-dualistic perspective.

It is erroneous to mix practical life and the practical world in the pursuit of truth. The ups and downs of the practical life within the practical world are nothing to do with the Soul, the Self.

In Self-awareness, nothing disappears on the dawn of wisdom, but the unreal nature of the waking is exposed in the midst of the duality. One sees his body as the consciousness, his ego as the consciousness, and the world as the consciousness. Thus, there is a unity in diversity in his understanding. 

In Self-awareness, the unknown restlessness disappears. Self-awareness brings stillness of the mind in the midst of action or duality.

Thus, searching the truth within illusion with the illusory Self, within the illusory world is bound to be an illusion. The illusion is created and sustained and finally dissolves as the Soul, which is present in the form of consciousness. Since there is no second thing other than the Soul or the consciousness; the consciousness itself is the ultimate truth or Brahman.

Advaitin sage and Maya:~

The King of the Hoysalas was a dualist and was greatly incensed at the doctrine taught Advaitin Sage that everything here below is an illusion. He wanted to teach the exponent of this doctrine a lesson. So he invited the then Advaitin sage to his palace. That Advaitin sage went there and stoutly maintained that everything in this world was an illusion. The king had arranged to let loose an infuriated elephant against, Advaitin Sage. The beast rushed at Advaitin 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 Advaitin Sage in the course of his flight, 'my running too is an illusion. Everything in this world is an illusion.

Remember:~

Similarly, the practical life within the practical world is merely an illusion. All our hopes and desires or pleasure and pain are a reality within the illusion. We all are searching for truth within the illusion, not being aware of the fact that the illusion is created out of single stuff which is the Soul or consciousness. 

The Soul is the innermost Self. When the waking entity realizes it is not the Self in the midst of the waking experience it enters the nondual Self-awareness, which is free from form, time, and space.

A Gnani is fully aware of ‘what is the truth’ and ‘what is untruth’. A Gnani e is fully aware of the fact that the experiences the pleasure and pain of the waking experience is merely an illusion because the waking experience itself is an illusion.

Thus, life within the waking experience will go on, on its own. It is nothing to do with the Soul, the Self. The waking or dream is merely an object to the formless witness. The Soul is the Self. The Soul is the witness. The Soul the witness is nothing to do with the three states because it is the witness of the coming and going of the three states or illusion.

When you are part and parcel of the illusion then it is foolish to question what is the purpose of the illusion because whatever belongs to the illusion is bound to be an illusion. the illusion hides the Soul, the Self, which is present in the form of consciousness. 

Remember: 

The life of a dream is a reality with the dream.  The dream becomes unreal when waking takes place. Similarly, the waking becomes unreal when you realize the ‘Self is not you but the Soul, which is present in the form of consciousness.

If the waking is unreal then your experience of birth, life, death, and the world within the waking experience also is unreal (illusion). 

The question is based on the waking entity (you or ego). Whatever is based on the waking entity (ego) is based on the dualistic perspective.

You have to learn to view the worldview from the non-dualistic perspective then only you will be able to have the Soulcentric view of the worldview. 

In Advaitic  Self-awareness, the ego is not considered as ego, even though the ego is present, the body is not considered as a body even though the body is present, the world which confronts him is not considered as world even though the world is present, the duality ceases even though the duality is present, because of wisdom everything is considered as consciousness. Thus there is conscious oneness.

Only in ignorance, the world in which we exist is an illusion created out of the Soul, the Self. 

Remember:~

The world is both real and unreal. It is real because it is a manifestation of consciousness, but is unreal, in the sense, that it is not absolute and eternal like consciousness itself.

People's approach is more practical, and they stuck with the reality of the world, they take it as real. That is why all the confusion.

The look of an object will depend upon the medium through which the observer views it. In fact, our mental and intellectual conditions determine the world, observed and experienced. The commoner viewing the world will see differently from a Gnani viewing the same world. Each one interprets the world that they see in terms of their existing knowledge. The commoner sees everything based on the ego, therefore, experiences the birth, life, death, and the world as a reality, whereas a Gnani sees everything as consciousness and he is fully aware of the fact that, there is no second thing that exists other than the Soul or consciousness. Thus, all the egocentric knowledge has to be bifurcated to realize the ultimate truth, which is beyond form, time, and space.

The world in which we exist is nothing but an illusion created out of the Soul, which is present in the form of consciousness.

The whole universe is nothing but the Soul. Therefore, there is no second thing that exists other than the Soul, which is present in the form of consciousness.

It is not as if something that was not consciousness suddenly becomes consciousness. Rather, "knowing the truth” means a removal of the ignorance about one's own existence as the consciousness. Thus, to "know the truth” is to "be consciousness."

The consciousness is ever-present. Without consciousness, the world, in which you exist ceases to exist. Consciousness is Self-evident. It is not established by extraneous proofs. It is not possible to deny consciousness because it is the very essence of the one who denies it. Consciousness is the basis of all kinds of knowledge, presuppositions, and proofs. Consciousness is everything. Thus, consciousness is the ultimate truth or Brahman. : ~ Santthosh Kumaar
