Well, Hinduism was never a religion... The usage of the word Hindu was further popularized by the Arabic term al-Hind referring to the land of the people who live across river Indus... So it was never a religion but a good way of life started by great saints and sages.. This way of life in sankrit is called 'Sanatan Dharma' meaning the 'eternal law' .. It includes various practises such as - the yoga system(linking yourself with the supreme), meditation, vegeterianism, breathing exercises(pranayam), bhakti(pure devotion), karma yoga etc...
At Hinduism is not a region, the followers do not have any specific name.
Hinduism is not one faith. Hinduism refers to multiple faiths or union of faiths of different people. As I have said before, it is a way of life. This 'way of life' is based on the guidance of the Bhagavad Gita(Song of God) and the Holy Vedas:
The Bhagavad-gita ("song of God")—the famous conversation between the peerless warrior Arjuna and the Supreme God, Krishna—posing as Arjuna’s charioteer—at the onset of the battle of Kurukshetra, circa 3200 B.C. Krishna explains all the essential spiritual truths: the difference between the soul and the body, the difference between the soul and the Supreme Soul (God), the science of reincarnation, the nature of time, the ultimate goal of yoga, why different kinds of religion appeal to different kinds of people, and the ultimate purpose of human life.
It is at times referred to as the "manual for mankind" and has been highly praised by not only prominent Indians such as Mohandas Karamchand Gandhi but also Aldous Huxley, Albert Einstein, J. Robert Oppenheimer, Ralph Waldo Emerson, Carl Jung and Herman Hesse. It is considered among the most important texts in the history of literature and philosophy.
Famous Reflections on the Bhagavad Gita:
Albert Einstein: When I read the Bhagavad-Gita and reflect about how God created this universe everything else seems so superfluous.
Mahatma Gandhi: When doubts haunt me, when disappointments stare me in the face, and I see not one ray of hope on the horizon, I turn to Bhagavad-gita and find a verse to comfort me; and I immediately begin to smile in the midst of overwhelming sorrow. Those who meditate on the Gita will derive fresh joy and new meanings from it every day.
Henry David Thoreau: In the morning I bathe my intellect in the stupendous and cosmogonal philosophy of the Bhagavad-gita, in comparison with which our modern world and its literature seem puny and trivial.
Dr. Albert Schweitzer: The Bhagavad-Gita has a profound influence on the spirit of mankind by its devotion to God which is manifested by actions.
Sri Aurobindo: The Bhagavad-Gita is a true scripture of the human race a living creation rather than a book, with a new message for every age and a new meaning for every civilisation.
Carl Jung: The idea that man is like unto an inverted tree seems to have been current in by gone ages. The link with Vedic conceptions is provided by Plato in his Timaeus in which it states..." behold we are not an earthly but a heavenly plant." This correlation can be discerned by what Krishna expresses in chapter 15 of Bhagavad-Gita.
Prime Minister Nehru: The Bhagavad-Gita deals essentially with the spiritual foundation of human existence. It is a call of action to meet the obligations and duties of life; yet keeping in view the spiritual nature and grander purpose of the universe.
Herman Hesse: The marvel of the Bhagavad-Gita is its truly beautiful revelation of life's wisdom which enables philosophy to blossom into religion.
Ralph Waldo Emerson: I owed a magnificent day to the Bhagavad-gita. It was the first of books; it was as if an empire spoke to us, nothing small or unworthy, but large, serene, consistent, the voice of an old intelligence which in another age and climate had pondered and thus disposed of the same questions which exercise us.
Aldous Huxley: The Bhagavad-Gita is the most systematic statement of spiritual evolution of endowing value to mankind. It is one of the most clear and comprehensive summaries of perennial philosophy ever revealed; hence its enduring value is subject not only to India but to all of humanity.
