Kundalini “rise into the sahasrara chakra but Kundalini is not the means to Self-awareness. +

The 'Self is not you but the Soul, which is present in the form of consciousness. The Soul is bodyless because it is a formless, timeless, and spaceless existence. the Kundalini theory is based on the body. 

The world in which we exist hides the Soul, the Self. the Soul, the Self is not within our body but the Soul is hidden by the world in which we exist. The Soul is hidden by the world in which we exist because the world in which we exist is merely an illusion created out of consciousness. thus the Kundalini theory based on the body is a false theory based on the false self(ego).   

Many think finding the source of the thoughts one becomes aware of the truth and they are not sure what thoughts are and where they come from. Thoughts are part of the illusion and thoughts will rise until the illusion remains a reality.  Therefore, seeking the truth in thought-oriented theories will not lead the seeker to know the ultimate truth.

Until and unless one becomes aware of the fact, how, or in what way the physical existence is an illusion, one will remain in the grip of duality, and base himself on physicality or intellectuality.  Intellectuality is a great hindrance in the pursuit of truth because it is based on the waking entity(physical self or ego).

There is a need to know the facts about the thought that; they are arising in duality or illusion. They are absent without the duality.  There is no need to be curious about what are they and where they come from continues to arise instead find the source of the illusion and the substance of the illusion to unfold the mystery of the mind/physical existence.

Remember:~

As intellectually elegant and edifying as all of these discussions of non-duality may be, they don't bring about true liberation because they are based on physicality. One has to mentally grasp the nondual truth to cross the threshold of duality.

Since people mix yoga and karma theory which is based on physicality it becomes difficult for them to understand and assimilate Self-knowledge.  If the body is not the self, and the true self is formless, then how the “Kundalini” will work when the self is not the physical body. 

If the body is not the Self, then where one has to trace those chakras in a formless Soul, the 'Self'.  If the body is not the 'Self' then the karma theory becomes meaningless because the action is part of the illusion.  Therefore, there is a need for a deeper understanding of the fact to assimilate the non-dual truth.

Until one has the conviction that the Self is the body he will remain experiencing the duality as reality. This duality is too powerful to be displaced by simple conversations. It needs deeper thinking and understanding and assimilation to overcome the duality.

One cannot bring the mind to total stillness without understanding “What is the mind?” and “What is the substance of the mind?”.

Yogic practice with correct posture to open the channels that allow the “Kundalini “rise into the Sahasrara chakra is not the means to Self-knowledge because it is based on physicality.  

When the Self is not the physical body, then the yogic practice is not the tool to acquire non-dual wisdom. It is merely imagining the non-dual nature of the Self/Soul and gaining the time-bound blankness of the mind. 

Remember:~

Yoga does not yield truth because it ignores the objective world. Say that yoga has its place rather than its value and that its value is for a certain type of mindset. One cannot live without the physical world; it is the basis of his life, so it must be the starting point of his inquiry. Things, not imaginations, must be the seeker’s material.

Yogi shuts his eyes against the world and then has the temerity to declare that he knows the world to be Brahman! Because he has not inquired into it, he knows nothing.

Yoga helps the yogi by giving him the feeling that the world, which confronts him is not worth bothering about, it detaches him from the world; it makes him treat the world as a dream, i.e. an idea. It does the same to his ego to some extent, because he becomes indifferent to what happens to him. But the great secret is that this is only feeling, he feels these things only but does not know that the world is an idea. Such knowledge can come only from deeper self-search and in no other way. That is why yogi cannot be Gnani.

Sage Sankara says: - Yoga is not the means of liberation (page 132-133 - Commentary on Brihadaranyakopanishad

Yoga can yield the only duality because everything that one can do or practice becomes a vanishing 'known.

It yields relative truth based on imagination, which is true from the dualistic perspective, not from the nondualistic perspective. 

It is the difference between feeling and knowledge. The feeling of the yogi that the world is unreal may change in the future because all emotions are liable to change; and the fact is that yogis do change, as when they indulge in accumulating wealth they lose their sense of the world unreality though previously they felt it.

 A permanent view of the world as unreal can come only after Soulcentric reasoning; such knowledge cannot change. Were the yogi of sufficiently sharp intellect he could discover the ideality of the world by Soulcentric reasoning alone and then it would not be necessary for him to have gone through yoga practice at all; that is why yoga is for dull or middling intellects.

Panchadasi: - The impossibility of yoga arrives at a successful end to its practices. (P.509 v, 109)

To realize the truth of the whole, one must know the world, which confronts him, otherwise, he gets a half-truth. The seeker of truth should not run away from the external world means the incapacity to think. Thus, it is necessary to know the nature of the world in which he exists.

The ultimate truth is attainable by perfect understanding, assimilation, and realization of ‘what is what’. The perfect understanding of ‘what is what’ leads to Advaitic  Self-awareness. : ~ Santthosh Kumaar
