Most of the orthodox families,  today live in the prison of superstition and dogmas.   The orthodox people expect their clan to follow a certain outdated religious code of conduct (Shastras) and live dogmatically following the traditional lifestyle. Orthodox people think that those who followed orthodox worship and rituals get Moksha.

According to Advaita Vedanta, the Veda addresses itself to two kinds of audiences - the ordinary ones who desire the transitory heaven and other pleasures obtained as a result of ritual sacrifices, and the more advanced seeker who seeks to know Brahman. 

Thus, the Purva mimam. sa, with its emphasis on the karma kanda of the Vedas, is meant for the first audience, to help lead its followers along the way. However, the Vedanta, with its emphasis on the jnana kanda, is meant for those who wish to go beyond such transient pleasures.

Their chosen path of orthodoxy is meant for the ignorant people who have a sheepish mentality and blindly accept the inherited dogmas and superstition. 

From the ultimate standpoint,  the concept of God itself is a  superstition. Thus,  all religious ideas of heaven, hell, sin, karma are mere imaginary theories meant for the ignorant people of ancient times.  

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.

First Mundaka - Chapter 2 (10):~  Ignorant fools, regarding sacrifices and humanitarian works as the highest, do not know any higher good. Having enjoyed their reward on the heights of heaven, gained by good works, they enter again this world or a lower one.

It is high time to stop judging who is right and who is wrong in this unreal world instead spend the same time to acquire Self-knowledge or Brahma Gnana or Atma Gnana to realize the world (Samsara) is unreal the Brahman alone is real.

The orthodox people are ordinary people. Thus, the ordinary ones who desire the transitory heaven and other pleasures are obtained as a result of ritual sacrifices. The karma kanda of the Vedas is meant for the ordinary audience, to help lead its followers along the way.

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)

Sage Sankara gave religious, ritual, or dogmatic instruction to the mass but pure philosophy only to the few who could rise to it. Hence,  the interpretation of his writings by commentators is often confusing because they mix up the two viewpoints. Thus, they may assert that ritual is a means of realizing Brahman, which is absurd. 

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 

When  Sage Sankara himself declares the scriptures dealing with rituals, rewards, etc. are, therefore,  addressed to an ignorant person then why should one follow the path of ignorance. -Adhyasa Bhashya 

Sage Sankara: ~ Atman, the innermost 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. 

So, they clearly indicate rituals and theories are not meant for those who are searching for higher knowledge or wisdom.   The path of wisdom is the only means. 

All the orthodox Advaitins indulge and immerse themselves in a ritualistic oriented lifestyle and follow the path of Karma and Upasana which is meant for lower and middling intellect and not for realizing the Advaitic truth.  

Many chose these orthodox scholars as their Gurus. But these Gurus are good to learn the conceptual Advaita meant for those Orthodox who believe their conduct-oriented lifestyle leads to Moksha (liberation).   

The orthodox Advaita is not the means to acquire Self –knowledge or nondual wisdom.  Those who are seeking the truth have to do their own homework to acquire Self-knowledge or Brahma Gnana or Atma Gnana. :~Santthosh Kumaar
