By eliminating the thoughts, ignorance will not vanish. Yogi eliminates all thoughts until he reaches the Samadhi.+

Some Gurus say that duality is a thought without knowing what duality is and what is nonduality.

By eliminating the thoughts, ignorance will not vanish. Yogi eliminates all thoughts until he reaches the Samadhi. Yogic Samadi is not Atmic-awareness.

The difference between the yogi and a Gnani both is vital, however: the Gnani inquiries into the world in which he exists and then regards it, arriving at the Soul ultimately: the yogi refuses to consider the world in which he exists and, therefore, arrives at a mere cipher, nothing, blankness, for he has not reduced the world, in which he exists into the consciousness.

 .
Every Yogi has to come out of the Samadhi and immediately dualistic illusion confronts him again. His peace goes, for it depended on the non-duality of Samadhi sleep. Hence, no yogi realizes the truth, which is beyond form, time, and space, but he only hallucinates about the formless nature of the Soul.

When one sees the second thing and though seeing it knows it to be none other than the consciousness, then he gets the Advaitic Gnana. On the other hand, yogic Samadhi is the non-seeing of the second thing; hence cannot yield Gnana, for the yogi does not see and does not know what the world is.

Remember:~ 

The thoughts arise to the dream entity within the dream world. The dream becomes unreal when the waking takes place. Similarly, the thoughts arise in the waking entity (you) within the waking world. The waking becomes unreal when  Advaitic wisdom dawns.

Advaitic Wisdom dawns when you realize the ‘Self’ not you but the ‘Self is the Soul, which is present in the form of consciousness. 

From the standpoint of the Soul, the world in which you exist is an illusion. Thus, the thought, the thinker, and the world in which the thinker exists is the dualistic illusion. the dualistic illusion is created out of a single clay. That clay is the Soul, which is present in the form of consciousness.

The thought, thinker, and the world in which the thinker exists have nothing to do with the Soul, which is the witness of the dualistic illusion.

There is no need to know to whom the thoughts come? Why do the thoughts come? All such questions have no meaning because the thoughts, thinker, and the world belong to the dualistic illusion. 

Whatever belongs to dualistic illusion has no value from the nondualistic perspective. Stick to the Soul, which is real and eternal, and drop the illusion. : ~ Santthosh Kumaar
