The point I was trying to make here is the though Vedas talk about a formless absolute but the Purva paksh(followers of Mimansa or Karma Kaand) have always rejected the Upanishadic concept of “Aham Brahm asmi”
Well, the Vedas themselves do not mention “aham brahmasmi” Vedanta is one particular interpretation of the formless absolute. And within Vedanta itself advaita is not the only school, but there is dvaita and vishvadvait. The Vedantins believe that bhakti and jnana yoga has the power to liberate. It is a more theistic branch of Hinduism.
The Mimansakas, on the other hand understand the formless absolute as the impersonal law of dharma and believe sound/shabd is eternal. To them the power of mantra and Vedic ritual consistent with the laws of dharma or karma yoga has the power to liberate. It is a ritualistic branch of Hinduism.
The Yogins believe that the formless absolute is a state of consciousness. To them raja yoga, tantra or kriya yoga in order to realise this state has the power to liberate. It is a mystical branch of Hinduism.
These schools are not really contradictory, they just view the formless absolute in different ways. A Hindu is not limited to either of them and can draw from all of them. Ultimately the goal is the same whether you are a vendatin, mimasaka or yogin. They all have their merits and demerits. I personally prefer Yoga.
I think part of the reason that nobody other than the mimanskas refer to the Vedas is because the Vedas are so difficult to read and understand and language is so arachic even the best of translators struggle and make mistakes and assumptions. However, there is no doubt that all of Hindu philosophy comes from the Vedas. The generals matter here not the particulars.
The whole of the Universe
Is stationed in the Omnipresent
And Omnipotent god.
We see him in various forms.
He brings to light
All these worlds .
Him they call the kala the infinite
Pervading the vast space
Atharva 19.53.3
Cast of anger
From your heart
Like an arrow from a bow
So that you may again be friends
And live together in harmony
Atharva 6.42.1
Perfect am I
Peferfect is my mind
Perfect are mine eyes
Perfect are my ears
Perfect is my breath
Perfect my entire being
At peace with myself am I
Atharva 19.51.1
O citizens of the world!
Live in harmony and concord.
Be organized and co-operative
Speak with one voice
And make your resolutions with one mind,
As our ancients saints and seers,
leaders and preceptors,
have performed their duties righteously
Similarly, may you not falter to execute
your duties
Rig 10.191.2
Not one of you is small
Not one a feeble child
All of you are truly great
Rig 8.30.1
Two birds(God and Souls)
With their beauteous wings
Associate in intimacy
Perch on the same tree
Of them, the soul, tastes its fruits
The other, god, enjoys without tasting
The knower of reality is he who knows
about the invisible thread running inside
the visible thread
Atharva 10.8.37
He who knows the first vital thread, binding
all the things formed in shape, colour and words,
knows only the physical form of the universe, and
knows very little.
But he who goes deeper and perceives the string inside
the string, the thin web binding separate life-forces with
cords of unity, knows the real entity.
Only he who knows the truly mighty omnipotent and omnipresent
god who is within and beyond all formulated entities of the vast universe.
Penetrate deeper to know the ultimate truth.
Atharva 10.8.38
The mind goes far away
To heaven and earth
Call it back to thyself,
so that it may remain
Under thy control
Rig 10.58.2
O Supreme Lord make me firm
And resolute like Thee
Bless that may look on me with a friendly eye
And I look on others likewise
May we experience complete harmony amongst us
Yajur 36.18
I know this Supreme Being
Who is beyond the limits of darkness
Yajur 31.18
The face of truth
Is covered by the glittering lid of gold.
The Purusha - the ultimate source of conscious life
Who shines in the sun
I am that Aum
The supreme entity
Yajur 40.17
The Supreme lord is too near
to be abandoned
Too close to be witnessed
Behold the natures splendour
And the Lords divine poetry
Both are beyond decay and death
Atharva 10.8.3
Eternity is space, eternity is the mid-air,
eternity is the mother, father and son.
Eternity is all that exists.
Eternity is the social consciousness
Eternal are all that have been born
And shall be born
Rig 1.89.10
He knows the truth who knows
That God is one.
Neither second nor third
Neither fourth is he called.
Neither fifth nor sixth
Nor seventh is he called.
Neither eigth nor ninth
Nor tenth is he called.
He surveys all that breathes and
breathes not.
He possesses the power supreme
He is the One
The One Alone
Atharva 13.514-21
The Supreme Being is is thousand headed,
thousand eyed, thousand footed;
He pervades the universe on all sides,
and extends beyond the 10 dimensions
He, indeed, is all this,
what has been and what will be,
He is the lord of immortality
transcending through material existence
Such is his magnificence, but the Supreme
Being is greater than this; all beings are a quarter
of him. Three quarters make up immortality in the
the supreme region.
Three quarters of the supreme being remain abstract,
one quarter part manifests again and again,
And diversified in form, it moves
to the animate and inanimate world
Through the divine energy of the Supreme being this
dynamic universe came into being(Virat)
Rig 10.90.1-5
O soul, blazing like the sun after cremation, having
reached the fire and the earth for rebirth, and residing
in the belly of thy mother, thou are born again
O soul, having reached the womb, again and again, though
auspiciously liest in thy mother, as a child sleeps in its mothers
lap
Yajur 12.38-39
The reason I have produced such a large frequency of hymns from the Vedas is to show you how clear it is that they contain all of the concepts of Hinduism already. These concepts are then later developed, systematized and turned into scientific systems by the darshanas.
Even verses from Bible & Koran can suggest the same Upanishadic concept of Brahman, that doesn’t mean they “merely expand the concepts in Upanishads”.
Nope, because Brahman is a panthestic god. The Bible and the Quran oppose such a conception of god vehemently.
