I quote scriptures because the scriptures are also saying the same thing that I am saying.

To realize the ultimate truth or Brahman, no scriptures are needed. I am highlighting only the rational views of the sage Sankara.

People think that by studying the Vedas, one will be able to get self-realization, but it is not so.

Vedic studies lead one nowhere. What is the use of studying scriptures when Upanishads itself declares:-

Katha Upanishad:~ This Atman cannot be attained by the study of the Vedas, or by intelligence, or by much hearing of sacred books. It is attained by him alone whom It chooses. To such a one, Atman reveals its own form. (Katha Upanishad Ch-II -23-P-20)

Mundaka Upanishad: ~ This Atman cannot be attained through the study of the Vedas, nor through intelligence, nor through much learning. He who chooses Atman—by him alone is Atman attained. It is the Atman that reveals to the seeker its true nature. (3 page-70 - Mundaka Upanishad- Upanishads by Nikilanada)

When the Upanishad says: the human goal is to acquire Self-Knowledge and they indicate the personal gods, scriptures, worship, and rituals are not the means to Self–knowledge, then why anyone should indulge in it.

The Upanishads declare:~

Mundaka Upanishad 1:2:8:~ “Remaining in the fold of ignorance and thinking 'we are extremely wise and learned,” the fools with boastful nature ramble about like the blind led by the blind alone.”

Mundaka Upanishad 3:2:3:- “The weak and timid cannot realize the Self. Self-realization is not possible through intellect or hearing spiritual discourse. One who welcomes God in every activity, through a thorough controlled and disciplined life, to him also the Soul is revealed

Katha Upanishad 1:2:23:~ The Soul cannot be realized through hearing the scholarly explanation of the discourses, not even by the intellect.

Katha Upanishad 1:3:6:~ “Through the knowledge of the Soul, God, one is pure and clean constantly.” Neither by reading the book nor by taking a bath at a holy place has one become pure. Inner purity is possible when one remains in constant touch with the Soul. Constant Soul Consciousness is the real purity.

Kena Upanishad 2:4:~ When it is known through every state of cognition, it is rightly known, for (by such knowledge) one attains life eternal. Through one's own self, one gains power, and through wisdom, one gains immortality.

Kena Upanishad 2:5:~ If here one knows it, then there is the truth, and if here one knows it not, there is a great loss. Hence, seeing the Real in all beings, wise men become immortal on departing from this world.

The scriptures are being added to from time to time. This process will go on. There is the final authority among them? One contradicts the other: duality reigns supreme.

The Upanishads are self-contradictory. Every pundit even gives conflicting interpretations of them. The final authority, therefore, is using one’s own reason. One should apply his reason to them.

The scriptures are for ignorant masses, who wholly accept the material world as it presents itself. Gnana is for those who have begun to realize that things are not what they seem. :~Santthosh Kumaar
