Yogi shuts his eyes the world confronts him and then has the temerity to declare that he knows the world to be Brahman! because he has not inquired into it the nature of the universe, he knows nothing.

Yoga helps the yogi by giving him the feeling that the world is not worth bothering about, it detaches him from world; it makes him treat the world as a dream. It does the same to his ego to some extent because he becomes indifferent to what happens to him. But this is only feeling, he feels these things only but does not know that the world is mere mirage. Such knowledge can come only after soulcentric inquiry and in no other way.

That is why yogi cannot be Gnani. It is the difference between feeling and knowledge. Feeling of the yogi that the world is unreal may change tomorrow because all emotions are liable to change; and the fact is that yogis do change, as when going after women they lose their sense of world unreality though previously they felt it.

A permanent view of world as unreal can come only after soulcentric reasoning; such knowledge cannot change. Were the seeker who is sufficiently sharpness he could grasp the unreal nature of the world by soulcentric reasoning alone.  To know whole truth, one must know the whole universe, otherwise he gets only half-truth.

Sanyasa is not the means to acquire Self-knowledge or Brahma Gnana.  Renouncing the worldly life and accepting sanyasa or monkhood means incapacity to think deeper, an impotency to inquire and reason.

First seeker   must inquire into the nature of the physical body i.e. matter. Second he must inquire into the nature of the mind.

Observe at everything in nature because in everything there is consciousness. One should not avoid them, do not shut his himself to Nature; and he should not shut himself away from the world which is as much consciousness, as anything else because the consciousness is the cause of  the three states and it itself is uncaused.

To say this world is illusion without first examining them and inquiring into them thoroughly is to delude yourself. The world is reality within the waking experience. Same way as the dream world was reality within the dream.  

The person, who stamped their foot on the ground to refute to show the world, is real, ignore that in dream he would do exactly the same--stamp his dream foot on the ground and assert it to be real. 

The dream becomes unreal when waking takes place. Similarly the waking becomes unreal when wisdom dawns. Wisdom dawns, when the waking entity indulges itself in deeper self-search and realizes the fact that, it itself is not the self. But the self is the formless witness of the three states.  The formless witness of the three states is the soul or consciousness, the innermost self.

Formless Consciousness also is the substance of the three states. Thus formless witness and substance of the three states are one in essence. Thus there is no second thing exists other than consciousness.   Thus formless consciousness (soul) is ultimate truth or Brahman.  Thus on the standpoint of the soul, the innermost self, all the three states are mere illusion. Whatever prevails without the illusion is ultimate reality or Brahman
