A perfect understanding of Sage Sankara removes all the obstacles blocking Self-realization. Sage Sankara is Advaita. Advaita is Sage Sankara.
The seeker of truth must discard all that is not needed for Self-realization. There is only one goal which is Self-realization. Stick to the truth the ignorance fades away on its own.
Sage Sankara says: ~ Atman is Brahman. The Atman alone is real is not religious truth. Sage Sankara declared this Advaitic truth, which is the ultimate truth to the whole world, many centuries back, is the rational truth, the scientific truth, and the ultimate truth.
Sage Sankara’s whole wisdom can be summed up in one sentence, ‘There is nothing else but Brahman.
Sage Sankara's that the Absolute Existence, Absolute Knowledge, and Absolute Bliss are real. The universe is not real.
Sage Sankara says that Brahman and Atman are one. The ultimate and the Absolute Truth is the ‘Self’, which is one thought appearing as many different individuals. The individual has no reality.
Only the ‘‘Self’’ is real; the rest, mental and physical are but passing appearances.
Without Advaitic wisdom, it is impossible to realize the truth, which is beyond form, time, and space. The all-pervading Reality is beyond both duality and non-duality.
Sage Sankara says: ~ The scriptures dealing with rituals, and rewards are therefore addressed to an ignorant person. Thus, the rituals are meant for ignorant people.
Sage Sankara: ~ "Though I wear these robes of a Sanyasin, it is only for the sake of bread."
~ This shows he was wearing the religious robe only for the sake of bread." Thus, it means those who are wearing religious robes for the sake of bread.
All the rituals based on the false belief of Gods will not yield any fruits and they are meant for the ignorant populace who are unable to grasp the God beyond the form, time, and space.
One of Sage Sankara’s missions was to wean people away from a ritualistic approach advocated by Mimamsakas and to project wisdom (jnana) as the means of liberation in the light of Upanishad teachings.
Sage Sankara criticized severely the ritualistic attitude and those who advocated such practices.
Scholar’s interpretations of sacred texts, the force of religious merit--none of these lead to the realization of that ultimate Truth or Brahman which is revealed in the clear reflection of the ‘Self’, engendered from contact with the knower of Brahman (Gnani).
Sage Sankara also said the study of the Upanishad not a prerequisite for attaining the human goal, the moksha.
Sage Sankara says:~ VC-162- There is no liberation for a person of mere book-knowledge, howsoever well-read in the philosophy of Vedanta, so long as one does not give up the false identification with the body, sense organs, etc., which are unreal.
People study Vedanta and they are under the delusion and conclude that they declare: ~
"I-Am-Brahman”, but they fail to realize the fact that Brahman is everywhere and in everything! The existence of Brahman is not limited to his physical identity because, it is the very essence of form, time, and space.
Sage Sankara strongly advocated the study of Upanishads, and at the same time cautioned that the study of Upanishads alone would not lead to moksha. In matters of such as spiritual attainment, one’s own realization was the sole authority and it cannot be disputed
Sage Sankara also said the study of Upanishad was neither indispensable nor a necessary pre-requisite for attaining the human goal, the moksha.
Sage Sankara says even those who were outside the Upanishad fold were as eligible to moksha as those within the fold were. He declared that all beings are Brahman, and therefore the question of discrimination did not arise. All that one was required to do was to get rid of ignorance (Avidya or duality).
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.
Sage Sankara: ~ VC Let erudite scholars quote all the Scripture, let Gods be invoked through sacrifices, let elaborate rituals be performed, let personal Gods be propitiated---yet, without the realization of one‘s identity With the Self, there shall be no liberation for the individual, not even in the lifetimes of a hundred Brahmas put together (verses-6)
Sage Sankara said: ~ Talk as much philosophy as you like, worship as many Gods as you please, observe ceremonies, and sing devotional hymns, but liberation will never come, even after a hundred aeons, without realizing the Oneness.
That is why Sage Sankara says: ~ VC 56. Neither by Yoga, nor by Sankhya, nor by good work, nor by learning, but by the realization of one's identity with Brahman is Liberation possible, and by no other means.
58. Loud speech consisting of a shower of words, the skill in expounding the Scriptures, and likewise erudition - these merely bring on a little personal enjoyment to the scholar but are no good for Liberation.
The study of the Scriptures is useless so long as the highest Truth is unknown, and it is equally useless when the highest Truth has already been known.
60. The Scriptures consisting of many words are a dense forest that merely causes the mind to ramble. Hence, men of wisdom should earnestly set about knowing the true nature of the Self.
61. For one who has been bitten by the serpent of Ignorance, the only remedy is the knowledge of Brahman. Of what avail are the Vedas and (other) Scriptures, Mantras (sacred formulae), and medicines to such a one?
62. A disease does not leave off if one simply utters the name of the medicine, without taking it; (similarly) without direct realization one cannot be liberated by the mere utterance of the word Brahman.
63. Without causing the objective universe to vanish and without knowing the truth of the Self, how is one to achieve Liberation by the mere utterance of the word Brahman? — It would result merely in an effort of speech.
64. Without killing one’s enemies, and possessing oneself of the splendor of the entire surrounding region, one cannot claim to be an emperor by merely saying, ‘I am an emperor’.
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.
66. Therefore, the wise should, as in the case of disease and the like, personally strive by all the means in their power to be free from the bondage of repeated births and deaths.
Then there is no need for the scriptures, religion, and religious ideas of God. One has to be more rational to realize the Advaitic truth, which is the ultimate truth or scientific truth.: ~Santthosh Kumaar
