'The foreigners (Muslim Turks),' says Vincent Smith, 'like their forerunners the Sakas and the Yueh-chi, universally yielded to the wonderful assimilative power of Hinduism, and rapidly became Hinduised.'
In this quotation Vincent Smith has used the words 'Hinduism' and 'Hinduised'. I do not think it is correct to use them in this way unless they are used in the widest sense of Indian culture. They are apt to mislead today when they are associated with a much narrower, and specifically religious, concept. The word 'Hindu' does not occur at all in our ancient literature. The first reference to it in an Indian book is, I am told, in a Tantrik work of the eighth century A.C., where 'Hindu' means a people and not the followers of a particular religion. But it is clear that the word is a very old one, as it occurs in the Avesta and in old Persian. It was used then and for a thousand years or more later by the peoples of western and central Asia for India, or rather for the people living on the other side of the Indus river. The word is clearly derived from Sindhu, the old, as well as the present, Indian name for the Indus. From this Sindhu came the words Hindu and Hindustan, as well as Indus and India.
The famous Chinese pilgrim I-tsing, who came to India in the seventh century A.C., writes in his record of travels that the 'northern tribes', that is the people of Central Asia, called India 'Hindu' (Hsin-tu) but, he adds, 'this is not at all a common name and the most suitable name for India is the Noble Land (Aryadesha).' The use of the word 'Hindu' in connection with a particular religion is of very late occurrence.
The old inclusive term for religion in India was Arya dharma. Dharma really means something more than religion. It is from a root word which means to hold together; it is the inmost constitution of a thing, the law of its inner being. It is an ethical concept which includes the moral code, righteousness, and the whole range of man's duties and responsibilities. Arya dharma would include all the faiths (Vedic and non-Vedic) that originated in India; it was used by Buddhists and Jains as well as by those who accepted the Vedas. Buddha always called his way to salvation the 'Aryan Path'.
The expression Vedic dharma was also used in ancient times to signify more particularly and exclusively all those philosophies, moral teachings, ritual and practices, which were supposed to derive from the Vedas. Thus all those who acknowledged the general authority of the Vedas could be said to belong to the Vedic dharma.
Sanatana dharma, meaning the ancient religion, could be applied to any of the ancient Indian faiths (including Buddhism and Jainism), but the expression has been more or less monopolized today by some orthodox sections among the Hindus who claim to follow the ancient faith.
Buddhism and Jainism were certainly not Hinduism or even the Vedic dharma. Yet they arose in India and were integral parts of Indian life, culture and philosophy. A Buddhist or Jain in India is a hundred percent product of Indian thought and culture, yet neither is a Hindu by faith. It is, therefore, entirely misleading to refer to Indian culture as Hindu culture. In later ages this culture was greatly influenced by the impact of Islam, and yet it remained basically and distinctively Indian. Today it is experiencing in a hundred ways the powerful effect of the industrial civilization, which rose in the west, and it is difficult to say with any precision what the outcome will be.
