Bhagavad Gita: 7: 19:~ "Such a man who has attained knowledge of Atman. Atman is God in truth. Atman alone exists. Everything is Atman; there exists nothing except Atman. Such a man is extremely rare."

The essential identity of the Atman and Brahman is the most important Advaitic declaration. The Atman or the Soul, which is present in the form of consciousness, is the ultimate truth or Brahman or God in truth. Consciousness is the hidden substratum of the whole universe in which we exist.

The Soul is the real Self, which is present in the form of consciousness. The universe in which we exist is the same and identical to consciousness because the universe is merely an illusion created out of consciousness. The illusion is nothing but consciousness.

Consciousness alone is real, and all else is merely an illusion. Whatever prevails without the illusion is real and eternal.

The Moksha (liberation) consists in realizing the Self, which is beyond the domain of form, time, and space. When one realizes the truth beyond the domain of form, time, and space, then the experience of birth, life, death, and the world is merely an illusion.  

Remember:~  

Self-realization is not just a matter of literal or intellectual understanding, but as something that is to be grasped and realized by the individual in his/her own personal realization. 

Manduka Upanishad:~ Yoga is in the sphere of duality and is unnecessary to one who knows non-duality.

Yogic practices will not help in acquiring Self-knowledge or Brahma Gnana or Atma Gnana. Yogic practices help only in repertory stages to be calm, to have patience and humility, and to keep away unwanted thoughts. But yoga is not the means to acquire Self-knowledge or Brahma Gnana or Atma Gnana because yoga is based on the chakras, which are within the body, whereas the Soul, the  Self, has no chakras. After all, it is ever formless, timeless, and spaceless existence.  

The practice of yoga is not recommended for seekers by Sages of truth. 

Remember:~ 

The seeker has to be equipped with requisite qualities such as patience, humility, ability to focus one's concentration in an intense manner, an ability to discriminate between the Real and the non-Real, and an intense urge for liberation  

It is important to remember that Moksha is not a result of ritualistic practice. Rituals are of the religion and personal Gods based on false Self within the false experience.   

Ritualistic practices are meant for the ignorant populace who are incapable of grasping the truth, which is beyond form, time, and space.  

Sage Sankara pointed out that those rituals could in no way bring about wisdom, much less Moksha.

The truth is hidden within the dualistic illusion. Ignorance is the cause of experiencing the dualistic illusion as a reality. : ~ Santthosh Kumaar
