The Advaitic orthodoxy is based on personal Gods whereas Sage Sankara’s Supreme Brahman (God in truth) is impersonal.+

The Advaitic orthodoxy is based on personal Gods whereas Sage  Sankara’s Supreme Brahman (God) is impersonal, Nirguna (without Gunas or attributes), Nirakara (formless), Nirvisesha (without special characteristics), immutable, eternal, and Akarta (non-agent). God is above all needs and desires. God is always the Witnessing Subject. God can never become an object as God is beyond the reach of the senses. God is non-dual, one without a second. God has no other besides it. God is destitute of difference, either external or internal. God cannot be described because the description implies a distinction. God cannot be distinguished from any other than God. In God, there is not a distinction between substance and attribute. Sat-Chit-Ananda constituted the very essence or Svarupa of God, and not just God's attributes. The Nirguna Brahman of Sage Sankara is impersonal.

Advaitic orthodoxy accepts the experience of birth, life, death, and the world as reality, whereas Sage Sri, Sankara declares the world is unreal Brahman alone is real.

Thus the experience of birth, life, and death happening within the unreal world are bound to be a falsehood. Thus, the religion and religious belief and its ritual based on the birth entity is bound to be a falsehood. Thus, the seeker has to realize ‘what is that is real and eternal?

Sage Sankara: ~ ‘Reality can be realized only with the eye of understanding, not just by a scholar. What the moon is like must be seen with one's own eyes. How can others do it for you?"~Vivekachoodamani

Advaitic Orthodoxy misinterpreted Sage Sankara and presented only the religious side of his teaching as the highest doctrine. Thus, people are misled.  The orthodoxy is based on rituals and mythical Gods and Karma. Advaitic wisdom of Sage  Sankara is nothing to with Advaitic orthodoxy.

Let Advaitic wisdom annihilate ignorance (I) and reveal Soul, the Self the God in truth.  Let your ears become deaf to the untruth propagated by the religion as a reality; enable you to realize the truth hidden by the ignorance (I).  Let your eyes become blind to illusion to receive the Soul as the Self as it is in the midst of the dualistic illusion.

All the orthodox ideas rejected by Sage Sankara. There is no need to indulge in rituals, in order to realize the ultimate truth or Brahman. There is no need to study philosophy, in order to realize the ultimate truth or Brahman then why do you indulge in studying philosophy.

Sage Sankara pokes fun at ascetics and points out that all their austerities do not cause desires to go (Altar Flowers" Page 205, v.2 P.207 v.4)

Sage Sankara pointed out those rituals could in no way bring about wisdom, much less moksha.

Sage Sankara says the rewards of the rituals are not a matter of direct realization. Advaitic wisdom is based on personal realization.

The orthodox Advaitin believes that rituals alone would lead one to higher levels of attainment. Further, the deities would reward only those entitled to perform the rituals alone. The entitlement involved the caste, creed, and other parameters.

The scriptural authority and value of rituals are part of the Advaitic orthodoxy, which is meant for ignorant people.

The Advaitic wisdom of Sage Sankara is nothing to do with the religion, caste, rituals, worships, yoga and other practices. Therefore an obvious disparity between what Sage Sri, Sankara‘s path of Gnana and path of Karma. The path of Gnana is meant for the advanced seeker of truth and the path of Karma is meant for the ignorant populace.

Even Sage Sankara appear and tell the orthodox people the path of orthodoxy is the path of ignorance they will not be able to drop their inherited samskara or conditioning, which they think is the only way to reach heaven and reap happy life in the next life.

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, and 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 the ‘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.-  (11- Adhyasa Bhashya)

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 still remain in ignorance of the Atman the real God.

As a person, one performs rituals throughout his life.  The person who performs rituals and aspires for rewards will view the world in which he exists as a reality. However, the Soul, the 'Self' is unborn eternal hidden by the world in which he exists.  From the standpoint of the Soul, the world in which he exists is merely an illusion. 

The scriptures dealing with rituals, rewards, etc. are therefore addressed to an ignorant person.

First Mundaka - Chapter 2 (9) - Children, immersed in ignorance in various ways, flatter themselves, saying: We have accomplished life's purpose. Because these performers of karma do not know the Truth owing to their attachment, they fall from heaven, misery-stricken, when the fruit of their work is exhausted.

First Mundaka - Chapter 2 (8) - Fools, dwelling in darkness, but wise in their own conceit and puffed up with vain scholarship, wander about, being afflicted by many ills, like blind men led by the blind.

Ish Upanishad declares:~ Those people who have neglected the attainment of Self-knowledge and have thus committed suicide 10/11/12

The religious orthodox people who have neglected the attainment of Self-knowledge and have thus committed suicide, as it were, are doomed to enter those worlds after death.

This is a condemnation of people who do not try to attain Self-knowledge. They are, in a real sense, committing suicide, for what can be worse than being a slave to sense enjoyment, completely oblivious of the real purpose of life, which is to be one ’s, own master?:~Santthosh Kumaar
