Knowledge of Atma is Adyatma. Advaita is Adyatma.+

Sage Goudpada: ~ To establish the truth of Non-duality by sheer reasoning alone. He begins by defining "What is real?" "What is unreal?" etc, because that is the right way to discuss or teach. People must first know what they are talking about. (Manduka Karika)

Adyatma is nothing to do with religious sects or creeds and religious beliefs or any philosophy or thinkers teaching. Adyatma is pure spirituality. Knowledge of Atma is Adyatma. Advaita is Adyatma. 

Adyatma is the knowledge of the truth beyond form, time, and space. Bifurcate religion, yoga, and theoretical philosophy and base the truth on the Athma it is Adyathma.

Adyatma is based on the ultimate truth which is based on the Atman or Spirit, which is the Self.

Sage Sankara's Advaitic wisdom is pure spirituality or Adyathma. 

The path of wisdom is divided into three parts:~

First: Hearing the truth--that the consciousness is the only reality and that the universe along with you is merely an illusion or Maya. 

Second: Reasoning upon these words of wisdom of Sage Sankara from all points of view. 

Third: Giving up all further argumentation and realizing the truth. This realization comes from being certain that consciousness is the ultimate truth or Brahman or God in truth. 

Look into the nature of the universe. And you will be able to see that universe by its very nature is illusory. The moment you understand that the universe is illusory, ignorance disappears and Self-awareness arises.

Self-awareness is the state of non-dual reality. That is the state of Advaita. People never realize non-dualistic awareness through religion and yoga.

Self-awareness raises only by mentally transcending the dualistic illusion into non-dualistic reality

Remember:~

The seeker has to have an inner urge to know the truth seriousness, patience, and humility in order to reach the ultimate end of understanding.

A man of truth will not indulge in the argument he keeps his distance with such a mindset.

Advaitic wisdom is soulcentric knowledge. It is difficult for people to understand soulcentric knowledge from a dualistic perspective. Our intelligence is based on the dualistic perspective thus; one has to learn to view and judge the worldview from the non-dualistic perspective.

As one goes on reading my blogs and posting gradually he will become soulcentric and will be able to view the worldview from the non-dualistic perspective and he will be able to grasp the Advaitic truth.

People’s opinions are based on the dualistic perspective based on the false self (ego or you) within the false experience (waking). Therefore, people go on arguing holding their accumulated knowledge as a yardstick.

The pursuit of truth is the pursuit of verification not the pursuit of an argument. Nothing has to be accepted as truth without verification.

The judgment has to be is based on the Soul, the Self to understand, assimilate and realize the truth, which is beyond the form, time, and space.

The judgment based on the nondualistic perspective leads to Self-awareness. In Self-awareness, the Soul, the Self, will remain in its own awareness in the midst of diversity.:~Santthosh Kumaar
