Upanishads ridicules worshiper of deities as a dim-witted person no better than the beast.+

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

Brihadaranyaka Upanishad declares: "He who worships the deities as entities entirely separate from the Self does not know the truth. For the Gods, he is like a pasu (beast)". (1. 4. 10)

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

The rituals, which are practiced in Hinduism, are not Vedic rituals and the Puranic gods are not Vedic gods.  Because: ~

The Vedas confirm God is Atman (Spirit), the Self.

Rig Veda: ~ 'Prajnanam Brahma'- Consciousness is the ultimate reality or Brahman or God in truth.

God in truth is the Atman, the Self. Atman is present in the form of consciousness.

Do not accept any other God other than Atman not worship other than Atman.

Let these words be inscribed in your subconscious.

Nothing is real but God. Nothing Matters but love for God in truth. God in truth is everywhere and in everything.

God in truth is hidden by the illusory universe. God in truth alone is and all else is an illusion.

Rig Veda: ~ The Atman (Soul or Spirit) is the cause; Atman is the support of all that exists in this universe. May ye never turn away from the Atman, the Self. May ye never accept another God in place of the Atman nor worship other than the Atman?" (10:48, 5)

Rig-Veda 1-164-46 and Y.V 32-1 clearly mention that God is “One”.

Rig Veda declares God is ‘ONE’ and God is Atman, then why believe and worship in place of real God.

Brihad Upanishad: ~ “If you think there is another entity, whether man or God there is no truth."

Yajurveda – chapter- 32:~ It has been said that God is Supreme or Supreme Spirit.

If God is the formless spirit, then how does the man know God created the world? There is no proof. If man had seen God creating the world, he could admit it, but how could he have seen God before he came into existence? (I.e. were created).

God is not physical. God is present in the form of the Spirit. The Spirit is the cause of the world and the Spirit itself is uncaused.

From the standpoint of the Spirit, the form, time, space and name are merely an illusion. The spirit alone is real and all else is an illusion.  In reality,  the spirit (God in truth) and matter (the world in which we exist) are one.

Bhagavad Gita: ~ Brahmano hi pratisthaham ~ Brahman (God) is considered the all-pervading consciousness (Spirit), which is the basis of all the animate and inanimate entities and material. (14.27).

When Bhagavad Gita says God is considered the all-pervading consciousness (Spirit) which is the basis of all the animate and inanimate entities and material then nothing has to be accepted as God other than consciousness. 

Lord Krishna says Ch ~V: ~ “Those who know the Self in truth.". The last two words (tattvataha) are usually ignored by pundits, but they make all the difference between the ordinary concept of God and the truth about God.

The dualistic worship of "God” is only for the ignorant populace. The God in truth is only Atman, the Self.   In reality,  there is no dualitY, no differentiation. Only Atman exists.

Brihadaranyaka Upanishad: ~ Brahman (God) is present in the form of the Athma, and it is indeed Athma itself.

Thus,  it proves that all the attributed gods are imagination because their existence is limited to the illusion because only an illusion, there is scope for imagination and diversity. Diversity is an illusion. Illusion is created out of a single substance, which is consciousness. Thus, consciousness alone is real and eternal.  Thus whatever is seen, known, believed and experienced as real within the illusion is bound to be a falsehood.   

And also in Yajurveda says:-

Translation 1

They enter darkness, those who worship natural things (for example air, water, sun, moon, animals, fire, stone, etc.).

They sink deeper in darkness those who worship sambhuti. (Sambhuti means created things, for example, table, chair, idol, etc.)- (Yajurveda 40:9)

Translation 2

"Deep into the shade of blinding gloom fall asambhuti's worshippers. They sink to darkness deeper yet who on sambhuti are intent."~ (Yajurveda Samhita by Ralph T. H. Griffith pg. 538)

Translation 3

"They are enveloped in darkness, in other words, are steeped in ignorance and sunk in the greatest depths of misery who worship the uncreated, eternal Prakriti -- the material cause of the world -- in place of the All-pervading God, But those who worship visible things born of the Prakriti, such as the earth, trees, bodies (human and the like) in place of God are enveloped in still greater darkness, in other words, they are extremely foolish, fall into an awful hell of pain and sorrow, and suffer terribly for a long time." :~(Yajur Veda 40:9.)

So, Yajur Veda indicates that:-

They sink deeper in darkness those who worship sambhuti. (Sambhuti means created things, for example,  table, chair, idol, etc. (Yajurveda 40:9)

Those who worship visible things born of the Prakriti, such as the earth, trees, and bodies (human and the like) in place of God are enveloped in still greater darkness, in other words, they are extremely foolish, fall into an awful hell of pain and sorrow, and suffer terribly for a long time." (Yajur Veda 40:9.)

 When the religion of the Veda knows no idols then why so many Gods and Goddesses with different forms and name are being propagated as Vedic gods. Why these conceptual gods are introduced when the Vedic concept of God is free from form and attributes.

It indicates clearly all the Puranic gods with form and name, and their worships and rituals were introduced by replacing in place of Vedic rituals and modified books of the code of conduct.   

Thus, the pure Vedic rituals have been replaced by the founders of the present-day Hinduism, the reason best known to them. When the Vedic goal is self- realization all these Puranic based understanding and knowledge is a misguided direction to the seekers of truth.

All the Puranic Gods belong to the dualistic illusion. The dualistic illusion is the product of ignorance.  The existence of the Puranic Gods are reality until ignorance prevails. :~Santthosh Kumaar
