What happens when thoughts are stilled?

Sri Sankara definitely says that:- Yoga is not the means of liberation on page 132-133 of his commentary on Brihadaranyakopanishad. 

What happens when thoughts are stilled? It is not the Self that is found. It is only mind. Therefore, through yoga, it is not possible to acquire nondual wisdom.   Therefore the yogi does not know ultimate t truth. Yoga is good to give peace and concentration, but only in order to start reasoning, i.e. thinking again to find truth. 

It is not enough to see a mere blank, in meditation. One has to see the body, ego and the universe as consciousness. One is free from ignorance not when he sees nothing at all, as in meditation but only when he sees the entire universe as consciousness. Hence one must know “What is mind, which appeared as universe?” in order to unfold the mystery of the mind. 

Yogic Samadhi are not the goal but a means to an end, i.e. wisdom. Yogic Samadhi in itself is useless, because the mind is withdrawn and there is no memory of it until after it is over and one returns to waking state. Yogi who attains mind control: it is only sleep. 

When Yogi comes out of Samadhi and immediately duality confronts him again. His peace goes, it was depended Samadhi-sleep. Hence no yogi attains true peace, but he imagines it.  

It is not possible know that a Yogi is self-realized because the yogic Samadhi is not self-realization.  One must first find out that what he has got is Samadhi or wisdom. Only through non-dual wisdom one gets self-realization.  The yogic Samadhi cannot be considered as non-dual wisdom. Therefore there is need to verify the facts.

 If a god men claims “I am god “No one can disapprove. Similarly with all other yogis who assert they know Brahman in Samadhi. There is no possibility of proof or disproof. Hence these yogis assume or imagine they are god and   they cheat themselves or others without knowing what god is in reality. 

The yogi fail to see non-duality in Samadhi, because he believes there is bliss to come to him from Samadhi. That shows he does not know truth, but still seeks bliss as something apart from himself. 

It is no use seeing God everywhere. One must see Atman, the same consciousness, the same self, everywhere, and then he will be able  to accept all the three states  alike(as consciousness), with sameness.
