Influence of Bhagavad Gita
The Bhagavad Gita has been highly praised numerous times not only by Indians but also people like Aldous Huxley, Henry David Thoreau, J. Robert Oppenheimer, Ralph Waldo Emerson, Carl Jung, Bulent Ecevit, Hermann Hesse, and others. The main source of the doctrine of Karma Yoga is obviously Bhagavad Gita. Albert Schweitzer found in Gita "a profound influence on the spirit of mankind by its devotion to God which is manifested by actions."
- Mohandas Karamchand Gandhi
The Bhagavad Gita's emphasis on selfless service was a prime source of inspiration for Mohandas Karamchand Gandhi. Gandhi told-"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".
- Sri Aurobindo
According to 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 civilization."
- Swami Vivekananda
Swami Vivekananda evinced much interest in Bhagavad Gita. It is said, Bhagavad Gita was one of his two most favourite books (another one was The Imitation of Christ). In 1888-1893 when Vivekananda was travelling all over India as a wandering monk, he kept only two books with him — Gita and Imitation of Christ.
- Aldous Huxley
Aldous Huxley, the English writer found Gita "the most systematic statement of spiritual evolution of endowing value to mankind.", He also felt, Gita 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."
- Jawaharlal Nehru
Jawaharlal Nehru, the first prime minister of India found that "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."
- J. Robert Oppenheimer
J. Robert Oppenheimer, American physicist and director of the Manhattan Project, learned Sanskrit in 1933 and read the Bhagavad Gita in the original, citing it later as one of the most influential books to shape his philosophy of life. Upon witnessing the world's first nuclear test in 1945, he later said he had thought of the quotation "Now I am become Death, the destroyer of worlds", verse 32 from Chapter 11 of the Bhagavad Gita.
- Henry David Thoreau
Henry David Thoreau wrote "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."
- Hermann Graf Keyserling
- Hermann Hesse
- Ralph Waldo Emerson
Ralph Waldo Emerson said this about the Bhagavad Gita: "I owed a magnificent day to the Bhagavad-Gita. 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."
- Wilhelm von Humboldt
Wilhelm von Humboldt pronounced the Gita as: "The most beautiful, perhaps the only true philosophical song existing in any known tongue ... perhaps the deepest and loftiest thing the world has to show."
- Bulent Ecevit
Turkish Ex prime minister Bulent Ecevit, when asked what had given him the courage to send Turkish troops to Cyprus . His answer was "He was fortified by the Bhagavad Gita which taught that if one were morally right, one need not hesitate to fight injustice".
- Lord Warren Hastings
The first governor general of British India wrote: "I hesitate not to pronounce the Gita a performance of great originality, of sublimity of conception, reasoning and diction almost unequalled; and a single exception, amongst all the known religions of mankind."
- Sunita Williams
Sunita Williams, an American astronaut who holds the record for longest single space flight by a woman carried a copy of Bhagavad Gita and Upanishads with her to space, said "Those are spiritual things to reflect upon yourself,life, world around you and see things other way, I thought it was quite appropriate" while talking about her time in space.
- Annie Besant
"That the spiritual man need not be a recluse, that union with the divine Life may be achieved and maintained in the midst of worldly affairs, that the obstacles to that union lie not outside us but within us—such is the central lesson of the Bhagavad-Gītā."-Annie Besant
