Yoga is only valuable tool to bring seeker to indifference to sensation and sense perception and thus prepare him for belief in and pursuit of perfection as an attainable goal.
The intellectuals cannot get over their tallest hurdle, not because they cannot see that the body is also part of the waking experience because they are so strongly attached to the body that they modify or fit their theories to please this attachment. In short, they refuse to give up the body. And they view, judge and concludes everything on the base of body [`I'] as self.
People, who think body and world are real, are fit for yoga and mysticism, which is for the middling class of intelligence. Those who grasp that body and world are within the waking and waking is mental and impermanent belong to the highest grade of intellects.

Desire, attachment, passion are regarded as handicaps to path of truth only because they prevent mind accepting truth that world is an illusion. People naturally will say they like to enjoy life. It is so beautiful and full of love and they refuses to regard it as a mere illusion," if they are so passionately attached to its reality and fully engrossed in it and refuse to inquire and reason, because of fear of losing their individuality. But they fail to realize the fact that, their individuality is dependent on their true identity, and their individuality is mere illusion, on the standpoint of their eternal deathless identity.
Pursuit of truth is not for those, who are incapable of grasping the truth that, waking is as real as dream. The dream is parallel waking experience and waking is parallel dream. The one who is able to grasp the fact that, the three states are not the experience of the waking entity, because waking entity is limited to the waking experience alone. And waking entity is absent in dream, and deep sleep. Therefore, seeker has to trace the knower of the three states, which comes and goes, and realize the fact that, the author of the three states is not the waking entity, but the formless witness, which is the soul/Ataman.

After long deeper persuasion the seeker will realize the fact that, the world is reality only on the base of the waking entity, only then he will be able to get the conviction that the three states are unreal.
It is absolutely necessary to know the fact that the waking and dream different from the mind/ 'I'. Thus they have to be regarded as mind/'I'.

No one can say when Ataman /true self / consciousness- -came into existence because it is eternal.
The mind has no place; it appears and disappears waking/dream; it is constantly changing. The waking and dream [mind/'I'] is created, sustained out of Ataman and finally dissolves as Ataman.
When the mind is limited to the physical entity due to ignorance it is individual mind/ego. Imaginations are based on individual mind/ego. Therefore, there is necessary to know the mind is the whole experience of waking/dream to proceed deeper in pursuit of truth.

Intellectuals may say the external world is a construction of the mind. But deeper inquiry and reasoning reveals the fact that causal relation is never found between subject and object, and then there is no sense in intellectuals claim.
The waking/dream are not mere egoistic imaginations, but they are appearances. This must be understood. In dream the most important thing is that it ha appeared spontaneously, in dream the dream entity may be a minister or a doctor, or a peasant, and it is imagined or constructed by the waking entity. It is not the idea of the waking entity, which is present only in waking experience, but the true self/soul, which is fully aware of the three states, which comes and goes in succession.
One may have seen the birth and death of other beings within the waking/dream, but one has never seen the birth and death of the knower/ seer witness of the three states.
One may imagine it but even that is possible within the waking/dream. In other words the formless witness of the three states must be there before their appearance. Hence the witness which is the true self, is termed "the unborn, because it is formless.
One has never seen the formless witness going, so one cannot call it mortal, because it is ever present in all the three states. It can remain with or without the experience of duality.
The three states [object] must be of the same stuff as the Seer [subject] of them because they disappear into soul/self/seer.

The common idea as soon as word "mind/'I' " is uttered is that it means "the mind of an individual" whereas in reality it means the whole appearance [waking/dream] ." This is an important and vital difference. Thus the mind/'I' is not the self, but the formless witness of the mind/'I' is the true self. It is wrong to say `I' am that, because I am refers to individuality. Thus individual experiences are within the `I', the self is beyond the `I'/mind as the witness of the `I'. The whole waking and dream are experienced by the formless soul, thus man cannot claim their authorship because he is within the waking or dream.
