Remember this; the Hinduism is not Ancient Vedic religion or Santana Dharma, which existed prior to Buddhism and Jainism.+

Supreme Court of India:~ Hinduism, as a religion, incorporates all forms of belief without mandating the selection or elimination of any one single belief,“ It is a religion that has no single founder, no single scripture and no single set of teachings. It has been described as Sanatan Dharma, namely, eternal faith, as it is the collective wisdom and inspiration of the centuries that Hinduism seeks to preach and propagate,” ---Hinduism has no single founder or scripture: SC, The Times of India (Delhi) Dec 17, 2015

Remember this:~ 

Hinduism is not Ancient Vedic religion or Santana Dharma, which existed prior to Buddhism and Jainism.

Hinduism is not the Ancient Vedic religion or Santana Dharma. And all Hindus indulge in non-Vedic practice barred by the Vedas introduced by the different founders of the different sects of Hinduism at a different time, whereas the Vedic religion or Santana Dharma is ancient and has no founder. Thus, all the non-Vedic caste-based belief systems founded by different founders of Hinduism have to be dropped in order to realize Ancient Vedic religion or Santana Dharma is nothing to do with the present-day Hinduism.

Hindus indulge non-Vedic beliefs such as idolatry, ancestor worship, pilgrimages, priestcraft, offerings made in temples, the caste system, untouchability, child marriages, and Sati. All these lack Vedic sanction therefore

The Vedic system did not have castes system. The caste system was a fake created in the name of Hinduism. This non~Vedic belief system called Hinduism has created hatred in the low caste Hindu for the higher caste is not the Vedic idea.

Brahmin was never a caste in the ancient Vedic society, and Chaturvarna was a professional classification and not a caste system as is being projected today.

Terming the original Chaturvarna system as the caste system is like saying that the classification of people as doctors, engineers, laborers today is a caste system.

To be considered an orthodox Hindu one need only accept the authority of Shruti, however, there is no universal agreement among Hindus what constitutes Shruti. Vedantins consider the Vedanta, i.e., the Upanishads as Shruti but also include the Bhagavad-Gita and Brahma Sutras as authoritative. For some Vaishnavas, the Bhagavata Purana is to be considered Veda. Some consider the Tantras are considered Veda. Thus, we find that there is ample scope for different philosophies and practices under the very broad umbrella of Hinduism.

The people of India adopted Buddhism, Jainism and many other splinter groups with non-Vedic ideologies with new beliefs, new Gods rituals, dogmas, and superstitions.

All the mythological heroes of the mythological stories projected as real God. All the mythological stories are nothing to do with Vedas. There is no mention of these mythological Gods in Vedas. Thus, the ancient Vedic religion or Santana Dharma was disappeared without a trace.

Reincarnation was not a Vedic belief. Belief in reincarnation which is central to Hinduism of today is not really attested to in the Vedas though they hint at life after death. The doctrine of transmigration as elaborated in Hinduism has no place in the Vedic hymns”. In the early Vedic literature, there is no express mention of the doctrine of transmigration.

It is in the Upanishads that it appears for the first time. The Rig Veda speaks of two paths for the Souls of the deceased, namely, the path of the Gods (devayana) and the path of the fathers (pitriyana). Those who go by the former enjoy immortality and there is no return to physical life after that.

In fact, the Vedic man longed for this state of life. Whereas those who go by the latter path, unite with the fathers and then return to earth, after having enjoyed the fruits of his deeds.

Rig Veda ~ consisting of about 10,500 verses ― there is only one occasion where there is mention of a return to this world after death. What is implied here is that it cannot be taken as important teaching of the Rig Veda.

The Avatara and caste system are not Vedic in origin. The theory of Avatara (‘descend’) of Gods which is very important to modern Hinduism is non-Vedic. The term Avatara (…) is not found in the earlier Vedic texts and is absent from the older Sanskrit glossaries

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.

The God of Santana Dharma or Vedic religion is Athma. Athma is the Soul, the innermost Self.

Rig Veda: ~ The Atman is the cause; Atman is the support of all that exists in this universe. May ye never turn away from the Atman the innermost 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: ~ “They call him Indra, Mitra, Varuna, Agni or the heavenly sunbird Garutmat. The seers call in many ways that which is One; they speak of Agni, Yama, Matarishvan.

Rig Veda 8/58/2:~ Only One is the Fire, enkindled in numerous ways; only One is the Sun, pervading this whole universe; only One is the Dawn, illuminating all things. In very truth, the One has become the whole world.

In Yajurveda – chapter- 32:~ It has been said that God Supreme or Supreme Spirit has no ‘Pratima’ (idol) or material shape. God cannot be seen directly by anyone. God pervades all beings and all directions. Thus, Idolatry does not find any support from the Vedas.

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

When Yajurveda says that God Supreme or Supreme Spirit has no ‘Pratima’ (idol) or material shape then whatever the Indian innocent populace believing and worshiping today are non-Vedic Gods. All the mantras and prayers are based on non~Vedic Gods.

On the Vedic perspective, all non-Vedic Gods are a myth. Worshipping myth in place of real God barred by Vedas.

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.

In Yajurveda gives clear-cut instruction what not to worship in place of God: ~

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. Giffith 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 prakrti -- the material cause of the world -- in place of the All-pervading God, But those who worship visible things born of the prakrti, 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.)

Yajur Veda clearly says 

Those who worship visible things such as the earth, trees, bodies (humans and the like) in place of God are enveloped in still greater ignorance, in other words, they are extremely foolish.

Sage Sankara says: ~ Ataman is Brahman. Thus, the Soul the innermost ‘Self’ is God. Therefore, all the Gods with form and attributes are mere imagination based on the false self. Thus, there are adulterations and add-ons in the past, which has to be bifurcated if one wants pure Vedic essence.

This clearly indicates the nature of the ‘Self’, which is the Soul. Thus, the Soul is the ultimate truth or Brahman or God. 

When the Soul is the ultimate truth or God why to indulge in worshiping the belief individualized God, which is not God. The Hindu belief system which came into existence after the 2nd century is nothing to do with the Vedas and Vedic religion.

The ultimate truth or Brahman is God in truth. God in truth is not the religious God we believe and worship.

Those who want to know the truth of the Vedic religion or Santana Dharma have to discard the non-Vedic belief system founded by different founders of Hinduism which propagates falsehood as truth.

When Sage Sankara himself declares: Ataman is Brahman (God in truth) then why to accept anything else as God other than Atman.

Sage Sankara is a Vedic Sage of universal order projecting his as non~Vedic Sage is a great sin. The Vedic truth is a pure spiritual truth. The essence of the Vedas is pure spirituality. Advaita propagated by Sage  Sankara is pure Spirituality. Advaita is nothing to do with Advaitic orthodoxy, which is meant for the ignorant populace. : ~ Santthosh Kumaar
