Sage Sankara says the rewards of the rituals were not matter of direct realization. The Advaitic wisdom is based on personal realization.+

Religious orthodox people think that they have accomplished life's purpose by indulging in rituals and sacrifices prescribed by the scriptures and advice of their Gurus but these performers of rituals and sacrifices do not know the Truth owing to their attachment they remain in ignorance.

There are two kinds of audiences ~ those who follow the Advaitic orthodox path are the ordinary ones who desire the transitory heaven and other pleasures obtained as a result of ritual, prayers, devotion to personal Gods and sacrifices. And the more advanced seeker who seeks to know the ultimate truth or Brahman.

The religion and yoga are meant for the ignorant populace, to help lead its followers along the way.

The path of wisdom meant for those who wish to realize the truth, which is beyond the form, time and space.

Those who lack the intelligence to discriminate between reality and the illusion will not be able to grasp what is real and what is an illusion. Both real and unreal are consciousness, not real alone. 

For those who have chosen the Atmic path have to drop all the orthodox adulteration bifurcation and dropping what is not needed to acquire ‘Self’-knowledge or Brahma Gnana or Atma Gnana: ~ 

The rituals mentioned in the karmakanda of the Vedas are sought to be negated in the jnanakanda which is also part of the same scripture. While the karmakanda enjoins upon you the worship of various deities and lays down rules for the same, the jnanakanda constituted by the Upanishads ridicules the worshipper of deities as a dim-witted person no better than a beast.

 This seems strange, the latter part of the Vedas contradicting the former part. The first part deals throughout with karma, while the second or concluding part is all about jnana. Owing to this difference, people have gone so far as to divide our scripture into two sections: the Vedas (that is the first part) to mean the karmakanda and the Upanishads (Vedanta) to mean the jnanakanda.

Sage Sankara:~  ‘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)

All the orthodox ideas rejected by Sage Sankara. There is no need to indulge 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 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 caste, rituals, worship, and other practices. Therefore an obvious disparity between 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 the 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, 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' 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.

Remember:~

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?

Ish Upanishads:-

MANTRA 10

Vidya and Avidya both are hindrances to Self-knowledge, but Vidya is even worse than Avidya. The word Vidya is used here in a special sense; here it means worshipping Gods and Goddesses. By worshipping Gods and Goddesses you will go after death to the world of Gods and Goddesses. But will that help you? The time you spend there is wasted because if you were not there you could have spent that time moving forward toward Self-knowledge, which is your goal. In the world of Gods and Goddesses, you cannot do that, and thus you go deeper and deeper into darkness.

Avidya is Karma and therefore a hindrance. You perform Avidya - i.e., you perform Agnihotra and other sacrifices. This is a roundabout way of purifying the mind, and it is also groping in the dark. But it may not have as heavy a toll on your time and energy as the other.

Ishopanishad: ~ “They are steeped in ignorance and sunk into the greatest depth of misery who worships the matter, instead of the All-Pervading God and those who worship things born of matter like trees, animals, man, etc. are sunk deeper in misery." : ~ Santthosh Kumaar
