Swami Vivekananda says: - The word Hindu is a misnomer; the correct word should be a Vedantins, a person who follows the Vedas.+

As we peep into Indian religious history we become aware of the fact that present-day Hinduism is not ancient Vedic religion or Santana Dharma

Aryans were ancient people who originally inhabited Central Asia and later migrated southwards to the regions stretching from Iran to northwest India. These early Aryans had a similar language, race, culture, and religion with many variations. The Aryans were influenced by the Dravidic culture and in later centuries other peoples also invaded and migrated to India bringing other influences and mixing many cultures' ideologies and beliefs. 

Ancient peoples of India belong to the Vedic religion or Santana Dharma, therefore, they have nothing to do with present-day Hinduism. The ancient peoples of Indus Valley or undivided India were called Hindus by Muslim Invaders. 

Vedic religion or Santana Dharma is not Hinduism. The word Hindu came originated from the word Sindhu which is another name for the river Indus. Maybe people who stayed along the Sindhu (Indus) valley came to be known as Hindus. 

An exact date of the birth of Santana Dharma cannot be given.  They say that Santana Dharma is as old as planet earth. Some claim it is 5000 to 7000 years old Ancient India consisted of indigenous people. 

 Aryans, Dravidians, Jews, Christian, and Muslims have invaded India and all ingenious people were converted to different faith from time to time.  Thus, Hinduism is a group of different caste, creeds, and faith.

The Hindus believed in polytheism, believing all of their Gods to be separate individuals, which were introduced much later by the founders of Hinduism which contains diverse beliefs caste, and creed.  Going to a temple would make one a follower of Hinduism.

The term ‘Hindu’ is originally a geographical nomenclature. In the Arabic texts where the term ‘Hindu’ is initially used, refers to the inhabitants of the Indian subcontinent, the land across the Sindhu or Indus River. Al-Hind was, therefore, a geographical identity, and the Hindus were all the people who lived on this land.

Thus, the term ‘Hindu’ was used to describe those who professed a religion other than Islam and Christianity. It is also noteworthy that the use of the word ‘Hindu’ in non-Islamic sources is known probably only from the 15^TH century A.D.

The term ‘Hindu’ became a term of administrative convenience when the rulers of Arab, Turkish, Afghan, and Mughal origin ~ all Muslims ~ had to differentiate between ‘the believers’ and the rest.

Aurobindo (1872-1950) believed that the Vedas are the foundation of the Santana Dharma.

Vedic religion or Santana Dharma is distinct from Hinduism. The Vedic religion or Santana Dharma deserves to be treated on its own as a distinct religion with its own sacred texts, rites, rules of social life, beliefs, and practices without interlinking it with Hinduism. Perhaps it is right to maintain that the Mimamsa School which is concerned with the investigation of the Vedic texts, their correct interpretation, and the meticulous performance of the Vedic rituals and ceremonies has preserved and defended a part of the heritage of the Vedic tradition.

The Vedanta school also may have received a part of the inspiration from the Vedas. For the rest of the Hindu philosophical schools and religious sects, the influence of the Vedas is nominal. However, in as much as elements from the Vedas have influenced some aspects of Hinduism, it may be considered as one of the many factors influencing Hinduism.

But by no means can it be maintained that Hinduism has its direct ancestry in the Vedic religion or Santana Dharma. Therefore, Hinduism of Vedic times is an imagined community. Hinduism is of a much later origin, and a historical view of Indian religions would endorse a dichotomy between Vedic religion or Santana Dharma and contemporary Hinduism.

Hinduism does not have a long ancestry as is often presumed or propagated by the Hindu ideologues. In fact, historically, religions like Buddhism and Jainism can claim greater antiquity than the Hinduism of today. Hinduism began to take a systematic form from the time of Sage Sri, Sankara (8^thcentury A.D). In this sense, he may be considered the ‘founder’ of Hinduism.

 Thus, Hinduism came into existence with its own code of conduct beliefs, rituals after the 8^th century.    Hinduism,  as one knows it today,  is of recent origin. He states: “Hinduism did not really achieve its status as a coherent, though still baffling, religious complex until after the establishment of the British rule in India.

In discussing the Vedic religion,  it is also to be remembered that in the course of history, many non-Aryan elements entered into the Vedic religion. The Vedic Aryans freely borrowed elements from the culture and the society around them. But we cannot say with precision, which are the non-Aryan elements in the Vedic religion. Therefore, the thesis of the direct ancestry of Hinduism of today from Vedic religion is to be considered as a myth purported by orthodoxy.

Sage Sri Sankara endeavored towards establishing the Vedic religion overthrowing Buddhism. But even he was not able to avoid the influence of Buddhism. The influence of the revolutionary atmosphere of Buddhism has reappeared in the Advaita of Sage Sri, Sankara. His inability to revive Vedic religion that flourished before the Buddhist revolution in its pure form is discernible.

Santana Dharma means that it has no beginning or an end, righteousness forever.

Swami Vivekananda says:~  The word Hindu is a misnomer; the correct word should be a Vedantins, a person who follows the Vedas.

In Encyclopaedia Britannica it says:~  The word Hinduism was first used by the British writers in the year 1830 to describe the multiplicity of the faiths of the people of India excluding the converted Christians. (Volume -20, Reference -581)

Pundit Jawaharlal Nehru:~  The word Hindu can be earliest traced to a source a tantric in the 8th century and it was used initially to describe the people, it was never used to describe religion. (The discovery of India” on pages -74 and -75) 

According to Pundit Jawaharlal Nehru, Its connection with religion is of late occurrence. The word Hinduism is derived from the word Hindu.

The word Hinduism was first used by English writers in the 19th century to describe the multiplicity of faiths of the people of India.

In the year 1794 A.D. Sir William Jones, the European chief justice of the then-Supreme Court of India at Calcutta, coined the new term Hinduism for the caste discriminating principle of Varnashrama Dharma originated based on Manu Dharma Śāstra.

It is a well-known fact that the Vedic people not only did not identify themselves as Hindus but also did not possess the essential characteristics of Hinduism. However, to legitimize the antiquity of Hinduism, Maharishi Sri, and Dayananda Saraswati (1824-1883) founder of Arya Samaj insisted on ‘going back to the Vedas’.

Maharishi Dayananda Saraswati founder of Arya Samaj was the first thinker and reformer to emphasize the importance of ‘going back to the Vedas’ to bring about social reforms in society and to purify Hinduism of its many aberrations. Hinduism is ‘Puranic based’. Vedic Gods like Indra, Varuna, Agni, Soma, and the like, whom the Vedic people worshipped, hardly have any significance in Hinduism.:~Santthosh Kumaar
