One of Sage Sankara’s missions was to wean people away from the ritualistic approach.+

Traditionally, religious people are so entangled in orthodox religiosity; it is very difficult for them to free themselves from narrow-minded prejudices and dogmas, and superstitions. 

These educated orthodox people are more ignorant than illiterate. They strongly stuck to their inherited orthodox baggage meant for the ignorant populace. Even though their own sage has said that orthodoxy is meant for the ignorant populace they ignore and they are like blind led by another blind follow the inherited blind belief.

Sage Sankara clearly indicates in Viveka Chudamani (2) that the Knower of the Atman (A Gnani) "bears no outward mark of a holy man" (Stanza 539).

But

Most Orthodox scriptural scholars are ignorant in the guise of Gnanis. One of Sage  Sankara’s missions was to wean people away from the 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. However, the texts that combined rituals with wisdom (jnana_karma_samucchaya) more in favor of the Mimamsaka position came into vogue, projecting Sankara as the rallying force of the doctrine.

Sage Sankara: ~ “Loud speech, the profusion of words, and possessing skilfulness in expounding scriptures are merely for the enjoyment of the learned. They do not lead to Liberation."

Mundaka Upanishads: ~ So-called spiritual pundits and learned are called children because a child takes whatever it thinks as truth. The question never occurs to children “Is what I have seen or thought real truth?" (P.334 line 9)

The Scriptures' mastery, the force of religious merit--none of these lead to the realization of that Ultimate Truth or Brahman. The ultimate truth is revealed in the clear understanding and realization of ‘what is the truth? and ‘what is the untruth? When one realizes the untruth (universe) is created out of single stuff, Self-awareness rises in the midst of duality exposing the unreal nature of the form, time, and space.

An adherent of the orthodox philosopher may say his philosophy teaches so and so", another man may object and say “No, his religious philosophy teaches such and such." Thus, they may go on uttering contradictions in the name of philosophy. True philosophy deals only with the appeal to facts, not theories.

Where scriptures and authorities do not agree with the reason, the seeker of truth must reject them.

How is one to know that the scriptures are true? The seeker has to look into the facts, for the proof of what has the worship of God done for the people! When a tsunami occurred in Japan God did not save the believers of Japan. Thus, God saves the one who prays such an argument is of no value in pursuit of truth.

People believe scripture is infallible, but deeper self-search reveals the fact that they are the mere book of words. The words are a mere expression of thoughts. Then it is impossible to see if the scripture-writers thoughts are founded in fact or not.

The fallacy of orthodoxy’s appeal to scripture lies in the varying and conflicting interpretations of the same scripture that different men feel entitled to give or hold.

The scriptures are for the ignorant masses, who wholly accept the practical life within the practical world as it presents itself. Gnana is for those who have begun to realize that things are not what they seem.

Where scriptures and authorities do not agree with the reason, the seeker of truth must reject them.

Scriptural knowledge is conceptual divisions invented by teachers of philosophy by their excessive analysis. All these concepts are a great obstacle in the pursuit of truth. Why should confusion be created and then explained away? Fortunate is the man who does not lose himself in the labyrinths of philosophy but goes straight to the source from which they all arise.

Remember:~

Mundaka Upanishad condemns rituals. The Para or Higher knowledge is the knowledge of the Supreme Being while the Apara or Lower Knowledge is that of following sacrificial rites and ceremonies. (1/2/ 1 – 6)

Remember:~

Physical & mental discipline such as Karma, Mantra Yoga, and Yajna, Puja Japa Blind devotion to deity or Guru is not the tool for liberation or freedom from experiencing the dualistic illusion as a reality. 

It is a dualistic cult including Advaitic orthodoxy propagates these disciplines. Such disciplines and codes of conduct have no value if one is seeking ultimate truth or Brahman to get Nondualistic Self-awareness. 

Mysticism, scriptural knowledge, penance based Scholasticism are the great hindrance to Self –realization. 

Inherited blind belief with corresponding actions based on scriptures, worship, ritual faith that imply certain mental and physical discipline, or scripture supporting the belief, faith, creed, ritual, theological knowledge personal or opinion leads to hallucinated knowledge. All these become a great hindrance to grasping, understanding, assimilating, and realizing the Advaitic or non-dual truth.

Scriptural mastery including ancient Sastras, Tarka, and Samkhya disciplines to support Karmas & belief Bhakti Argument & interpretation with the help of logic, grammar, etc.

to support beliefs, revelations, prayers, etc. In addition, dogmas, theological or other based on authorities.

That is why 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) Vivekachoodamani v 56, pg~25

Sage  Sankara says:~ The scriptures dealing with rituals, rewards are therefore addressed to an ignorant person.-Adhyasa Bhashya 

Sage Sankara:~ (11) As regards the rituals, Sage Sankara says, the person who performs rituals and aspires for rewards will view himself in terms of the caste into which he is born, his age, the stage of his life, his standing in society, etc. In addition, he is required to perform rituals all through his life. However, the 'Self' has none of those attributes or tags. Hence, the person who superimposes all those attributes on the changeless, eternal Self and identifies Self with the body is confusing one for the other; and is, therefore, an ignorant person. The scriptures dealing with rituals, rewards, etc. are therefore addressed to an ignorant person.-Adhyasa Bhashya 

Sage  Sankara:~ (11.1) This ignorance (mistaking the body for Self) brings in its wake a desire for the well-being of the body, aversion for its disease or discomfort, fear of its destruction, and thus a host of miseries(anartha). This anartha is caused by projecting karthvya(“doer” sense) and bhokthavya (object) on the Atman. Sage Sankara calls this adhyasa. The scriptures dealing with rituals, rewards, etc. are, therefore, he says, addressed to an ignorant person.-Adhyasa Bhashya 

Sage Sankara:~ (11.2) In short, a person who engages in rituals with the notion “I am an agent, doer, thinker”, according to Sage Sankara, is ignorant, as his behavior implies a distinct, separate doer/agent/knower; and an object that is to be done/achieved/known. That duality is avidya, an error that can be removed by Vidya.-Adhyasa Bhashya 

Sage Sankara: ~ (12) Sage Sankara affirming his belief in one eternal unchanging reality (Brahman) and the illusion of plurality, drives home the point that Upanishads deal not with rituals but with the knowledge of the Absolute (Brahma Vidya) and the Upanishads give us an insight into the essential nature of the Self which is identical with the Absolute, the Brahman.-Adhyasa Bhashya 

Sage Sankara: ~ Atman, the Self is verily Brahman (God), being equanimous, quiescent, and by nature absolute Existence, Knowledge, and Bliss. Atman is not the body that is non-existence itself. This is called true Knowledge by the wise.

Everyone’s inner work is on. The Soul is the Self. The Soul the inner Guru guides us all till we get the stillness of its Advaitic true nature. It is the Soul that is in ignorance it is the Soul that has to wake up from the sleep of ignorance. : ~Santthosh Kumaar
