Sage Sankara indicated that, the ultimate truth lies beyond the religion, the religious concept of God and the scriptures.+

Advaitic wisdom does not come just by sitting quietly, observing silence, and meditating, reading books, hearing sermons, meeting gurus or yogis, and doing pranayama, but wisdom dawns only when you realize the fact that the ‘self’ is not you, but the ‘self’ is the formless Soul. 

Self-knowledge cannot be attained by the study of the scriptures and intellectual understanding or by bookish knowledge.  Therefore, there is no use in studying the scriptures and other scriptures in order to acquire non-dual wisdom.  That is why Buddha rejected the scriptures, and even Sage Sankara indicated that the ultimate truth lies beyond religion,  the religious concept of God, and the scriptures.

There is only one Reality to be known, the same for all seekers, but the ways to it, are hidden by the religion.  Self-discovery is the only way, towards non-dualistic absolute without any religious doctrines, which will help the seekers to unfold the mystery of the illusion in which we all are searching for the truth of our true existence.

Sage Sankara:~  VC~ 65. As a treasure hidden underground requires (for its extraction) competent instruction, excavation, the removal of stones and other such things lying above it, and (finally) grasping, but never comes out by being (merely) called out by name, so the transparent Truth of the self, which is hidden by Maya and its effects, is to be attained through the instructions of a knower of Brahman, followed by reflection, meditation and so forth, but not through perverted arguments.

'To realize the Advaitic Truth a freer and fuller scope the seeker has to realize the form, time and space are one in essence. And that essence is consciousness. And the Soul the innermost self is present in the form of consciousness.   

To realize the Advaitic truth the seeker has to be free from all superstitions and orthodox contamination. The seeker must dedicate himself to  acquire Self-knowledge or Brahma Gnana or Atma Gnana   alone.'

Amrita-Bindu Upanishad:~   An intelligent person, who has studied the scriptures and has practiced what they enjoin should discard them after experiencing Brahman as his Self, just as a man discards the husk when he has found the grain’.

Brihadaranyaka Upanishad:~  A wise man, having realized Brahman as his Self, should keep his higher intuitive faculty (prajna) united with Brahman. He should not oppress his mind with many words, for they are a mere waste of energy.

Advaita is not a philosophy. Advaita is the nature of the Soul, the Self.  There is no need to study any philosophy to realize the ultimate truth or Brahman.  The Soul, which is present in the form of consciousness, is the ultimate truth or Brahman.

All the philosophies and all the teachings on nonduality are based on the dualistic perspective. Such teachings are mere imaginary nonduality from the dualistic perspective.

In Self-awareness the Soul will be in the objectless –awareness in the midst of the duality (objects) and then the sense of duality will cease to exist as a reality.

Where was the ‘I’ in deep sleep?  The nature of the Soul is like deep sleep. Deep sleep is still a state of ignorance because we become aware of the deep sleep in the waking experience, which is the state of ignorance. In Self-awareness, all three states are one in essence.

The ‘I’ is present only when the waking or dream is present. The ‘I’ which appears as disappears is merely an illusion.  Individuality is a reality only from the dualistic perspective. From the non-dualistic perspective, there is neither the individual nor the world exists is a reality.

When one says "Nothing is" what is the meaning of "is"? "Nothingness” is something that exists: one cannot prove that consciousness does not exist.

The mind is nothing but an objective existence.   The seeker has to eliminate all the objective knowledge through wisdom and then objectless knowledge will alone remain. This is the nature of the Soul, the Self.

 Brihad Upanishad says: ~ “Every man says “I know.” What does he know?

The word ‘One’ is not understood anywhere except in the Advaitic path. ‘One’ always means two when analyzed. Hence, the Upanishads are careful to show they do not mean this monism, but ‘One’ without a Second" i.e. Advaita. No philosophers of the world have seen this point. Monism is really pseudo-monism, i.e. duality.  Monism is not Advaita. Monism is a religious fable.

Advaita cannot be spoken…it means not two. There cannot be any division. In Advaita…hence, the moment it is spoken like any other subject the whole point is lost.

 The Advaitic truth is beyond the domain of the duality. Beyond the domain of the duality, means beyond the domain of the form, time, and space. Beyond the domain of the form, time and space mean, beyond the experience of the birth, life, death, and the world. Beyond the experience of birth, life, death, and the world then there is only the unity in diversity or oneness or Advaita.

Just by saying, keep quiet, do nothing more, just keep quiet or be silent,  the thoughts will not vanish.   Only when wisdom dawns, the Soul, the Self, remains in its own awareness.  

In Self-awareness the mind becomes still because there is no division in the consciousness, there is a oneness in the midst of the dualistic illusion or Maya.  Thus, without the Advaitic wisdom, it is impossible to realize that form, time and space are one in essence. 

Science is the highest teaching in the world of duality. Spirituality has its roots in the same world but ultimately leads to Advaitic or non-dualistic awareness.:~Santthosh Kumaar
