Non-Vedic beliefs practices barred by the Vedas introduced by the different founders of the different sects of Hinduism at a different time.+

The Vedas do not talk about idol worship; the followers of Vedic Religion or Santana Dharma never worshiped idols. 

God is a formless, timeless, and spaceless existence. Thus according to the Vedas God neither has any image nor God resides in any particular idol or statue. God cannot be seen directly by anyone. God pervades all beings and all directions.    

                              

From the Vedic perspective, Lord Krishna has been just a Mahan yogi and not God himself. Because in the Bhagavad Gita itself’ says: ~

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

So, from a Vedic perspective, Lord Krishna is not a Vedic God because Rig Veda says:   May ye never accept another God in place of the Atman nor worship other than the Atman?"

That is why 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.

Non-Vedic beliefs and practices are barred by the Vedas introduced by the different founders of the different sects of Hinduism at different times, whereas the Vedic religion or Santana Dharma is ancient and has no founder.

Hinduism is not Vedic religion or Santana Dharma.  Hindus do idol worship, while Vedas bar idol worship.

The Vedas do not talk about idol worship. In fact, till about 2000 years ago followers of Vedism never worshiped idols. Idol worship was started by the followers of Buddhism and Jains. 

There is logic to idol worship. Vedas speak of one God that is the supreme ‘Self’ i.e. Atman or Soul but Hinduism indulges in worshiping 60 million Gods.

The Hindus believed in polytheism, believing all of their Gods to be separate individuals, which was introduced much later by the founders of Hinduism which contains diverse beliefs caste, and creed.  

When the Vedic religion or Santana Dharma knows no idols then why so many Gods and goddesses with different forms and names are being propagated as Vedic Gods. Why these conceptual Gods are introduced when the Vedic concept of God is free from form and attributes. 

Hindus do idol worship, while Vedas bar idol worship.   According to Vedas, God pervades everything and everywhere.

People, who worship the belief of God, are hallucinating that they become one with such God because they believed the false God as God in truth. 

To be considered an orthodox Hindu one need only accept the authority of Shruti, however, there is no universal agreement among the Hindus on 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 ideologies,   philosophies, and practices under the very broad umbrella of Hinduism.

Hindus indulge non-Vedic beliefs such as idolatry, ancestor worship, pilgrimages, priestcraft, offerings made in temples, the caste system, untouchability, and child marriages. All these lack Vedic sanctions, therefore, Hinduism is not Ancient Vedic Religion or Santana Dharma.

Remember:~

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 ‘Self’. May ye never accept another God in place of the Atman nor worship other than the Atman?" (10:48, 5)

Yajurveda – chapter- 32:~  God is 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 in truth) is in the form of the Athma, and it is indeed Athma itself.

 When Upanishads and Vedas declare that, “God is the form of the Athma, and it is indeed Athma itself’ then why accept another God in place of the Athma or worship other than the Athma.

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 prakrti, 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.)

Thus, to acquire ‘Self’-knowledge or Brahma Gnana or Atma Gnana, the seeker has to realize his inherited religion is adulterated in the past and it becomes a great obstacle is realizing the ultimate truth or Brahman or God.     : ~ Santthosh Kumaar
