First Mundaka - Chapter 2 (10) - Ignorant fools, regarding sacrifices and humanitarian works as the highest, do not know any higher good.+

Religions hold birth, life, death, and the world as a reality. From the ultimate standpoint, the world in which we exist is an illusion created out of the Soul, which is present in the form of consciousness. Advaitic sect holds the world (illusion) as a reality whereas Sage Sankara says the world as an illusion.

The individual experience of birth, life, death, rebirth, sin, karma and personal gods and rituals belongs to the illusion.

Advaitic religious sect is a path meant for the ignorant populace, which is incapable of grasping the Advaitic wisdom hidden by the Maya or illusion.

The seeker must know the difference between religion and spirituality. Many people think the religion itself as Spirituality or Adyathma.

Religious orthodox think that through their good karma and performing rituals they get moksha but it is not so

The Karma Theory is the theory of ignorance and is meant for the ignorant populace. Karma (Action) will not dispel ignorance itself. Karma itself is based on ignorance Only Self-Knowledge or Brahma Gnana or Atma Gnana will destroy ignorance.  

Sage Sankara says:~ the world as unreal. Therefore, how actions performed in the unreal world can get Moksha or freedom. Therefore there is a need to know the fact that, the Self is not physical but the Self is the Spirit to understand and assimilate and realize the truth beyond physicality.

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.

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.

Remember:~

The ‘Self’ is not you but the Self is the Soul, which is present in the form of the consciousness. The karma theory is based on the birth entity whereas the Soul is birthless and deathless because it is the ever-formless, timeless and spaceless existence. The Soul, the innermost ‘Self’ is not limited to you because it pervades everything and everywhere in the world in which you exist.

The Karma theory is based on form, time, and space. Without the form, time, and space the doer, doing and the world cease to exist. 

From the standpoint of the Soul, form, time and space are an illusion. If the form, time, and space are an illusion the doer, doing and the world are bound to be an illusion. Thus, the karma theory is based on the illusory reality that is bound to falsehood.

The individual experiences within the practical world are a reality only within the waking experience but the waking experience itself is an illusion created out of consciousness. If the waking experience is a mere illusion then practical life within the practical world is bound to be an illusion.

The karma theory is not meant for those who have chosen the religious and yogic paths which are based on the birth entity whereas the Atmic path is pure spirituality based on the unborn Soul, the  Self, which is ever nondual.

 Sage Goudpada says: - The merciful Veda teaches karma and Upasana to people of lower and middling intellect while Jnana is taught to those of higher intellect.

The Atmic path or the path of wisdom is an independent path. The Soul has no karma, therefore; the karma theory is nothing to do with the Soul, which is birthless and deathless.

Thus, the experience of birth, life, death, and the world is a dualistic illusion. The Advaitic orthodox people are stuck with the karma theory and rituals are stuck with the theory meant for the lower mindset think by glorifying their guru and conceptual god and indulging in all sorts non-Vedic (Puranic) rituals they get Moksha. :~Santthosh Kumaar
