It really depends on people's inborn natural capacity to understand and assimilate Sage Sankara's Advaitic wisdom.+

With the sharp razor of the Advaitic wisdom, the seeker can easily overcome the ignorance of his true existence, which is free from the illusory experience of form, time, and space.

The pursuit of truth is for the purpose of Self-Realization. Perfect understanding of ‘What is what’, leads to realizing the truth, which is beyond the form, time, and space.

Self-knowledge has to be acquired by the direct realization of the ultimate truth. In the realm of the ultimate truth, the intellect which is based on the ego ceases to function. The seeker realizes that the Mind and the Soul are one in essence and that essence is consciousness.

The Soul is the innermost Self. The Soul is present in the form of consciousness. Consciousness itself is the knower, known, and knowledge.

By realizing consciousness as the ultimate truth or Brahman, the distinction between knowledge, the knower, and the known vanishes.

Inner urge to know the truth, sharpness to grasp, humility, receptiveness, and courage to drop all the egocentric accumulated knowledge, are requisite for the inner (mental) journey.

Remember:~

The Soul, the Self, is God. The Soul, which is present in the form of consciousness, is Infinite. Consciousness is all-pervading. The world in which we exist is nothing but consciousness.

Sage Sankara’s wisdom is not teaching or philosophy but Advaita is the universal wisdom. Advaitic wisdom is neither a teaching nor a theory but it is mere guidance to those who are seriously seeking the ultimate truth or Brahman.

Grasping the ultimate truth anytime, at any age, if the seeker has the spiritual maturity and capacity to grasp it.

Sage Sankara says: ~ VC-47- All the effects of ignorance, root, and branch, are burnt down by the fire of knowledge, which arises from discrimination between these two—the Self and the not-Self.

It really depends on people's inborn natural capacity to understand and assimilate Sage Sankara's Advaitic wisdom.

Swami Vivekananda: ~ “Advaita encompasses everything. Since Advaita requires heavy-duty intellectualism, it had to be progressively simplified.  

Sage Sankara’s wisdom is a Self-examiner, to test oneself to discover how near to Gnana he has approached what progress has already been made on the path, and what still remains to be done. It sets up criteria for Self-judgement. There are millions in search of truth but one in a million will be able to grasp it.

Without Sage Sankara, there is no Advaita (nonduality). Since it was mixed up with orthodoxy there is a lot of confusion.

I am highlighting all the obstacles, which are blocking one from realizing the ultimate truth or Brahman.

There are so many non-dualistic masters of the East and also from the West who expound Advaitic or non-dualistic knowledge but none of them are helpful to reach the ultimate end of the inner core of existence.

One has to know and realize that the Self is the Soul and identify it as his true identity to find liberation from the bondage of the illusion of birth, life, death, and the world(duality). The goal of our life is to find and realize our identity with our Soul, which is our Self.

If you are serious and sincerely seeking truth then that very serious sincerity will help you to realize what is truth and what is the untruth. Self-discovery leads to Atmic-awareness.

Upanishads: - Fools dwelling in darkness, but thinking they wise and erudite, go around and round, by various tortuous paths, like the blind led by the blind. (Upanishads Nikilanada - Ch II-5 P-14)

The scripture's mastery, the force of religious merit--none of these leads to the realization of that ultimate truth or Brahman.

The ultimate truth is revealed in the clear understanding and realization of ‘what is truth and ‘what is untruth'.

When one realizes the untruth (universe) is created out of a single stuff, Self-awareness rises in the midst of duality exposing the unreal nature of the form, time, and space.

People think by studying Vedanta thoroughly, they are under the delusion and conclude that they have become Gnanis.

Becoming adept in Advaita Vedanta does not mean that one has become Gnani. One gains thereby a mere intellectual understanding of the truth. The truth is e beyond the intellect.

Sage Sankara said: -Neither by the practice of yoga nor philosophy, nor by good works nor by learning, does liberation come, but only through the realization that Atman and Brahman are one in no other way.(1) VivekaChudamani v 56, pg 25

Fortunate seekers are the ones who do not lose themselves in the labyrinths of philosophy. conceptual divisions invented by the Advaitic Gurus of the East and the West by their excessive analysis. there is no end to concepts, they create more confusion.

The serious seeker is the one who does not lose himself in the labyrinths of philosophy but searches for the 'Self' independently and realizes it.

Among thousands of people, scarcely one strives for perfection; and of those who strive and succeed, scarcely one knows the ‘Self’ in truth. The truth is beyond form, time, and space. Come ye slow, or come ye fast; it is but the Soul that reveals ls itself at last.: ~ Santthosh Kumaar
