The religions of India have intrigued the West for millennia, but it was only in the 19th century that accurate and relatively comprehensive information regarding the teachings and practices of Hinduism and Buddhism appeared in Europe and the United States. Indian philosophical doctrines began to influence Western thinkers such as Arthur Schopenhauer, Henry David Thoreau, Ralph Waldo Emerson, and Friedrich Nietzsche. The most influential of these doctrines were Hindu monistic beliefs, which maintain that the cosmos is wholly sacred or participates in a single divine principle (brahman, or Being itself). Esoteric groups—such as the Theosophical Society, founded by Helena Petrovna Blavatsky, and its many offshoots—integrated Indian philosophical and religious concepts into a synthesis that also drew on Western mysticism, Neoplatonism, Kabbala, religious monism, and communication with the spirit world.

By the end of the 19th century, the first religious group to be imported from India took root in the United States, when Vivekananda attended the 1893 World’s Parliament of Religions in Chicago and then founded the Vedanta Society in New York City. Based on the monistic teachings of one of Hinduism’s philosophical schools and on its interpretation of the teachings and mystical experiences of Vivekananda’s teacher, Ramakrishna (1836–86), the Vedanta Society attracted the attention of many prominent members of the artistic community: the French actress Sarah Bernhardt, the American author and publisher Paul Carus, the English novelist Aldous Huxley, and the Anglo-American novelist and playwright Christopher Isherwood, among others. With centres in India and throughout the world, the Vedanta Society (also known as the Ramakrishna Mission) promotes a highly eclectic and tolerant form of religious unity. It claims that all world religions teach fundamentally the same truth but nevertheless maintains that Vedanta is uniquely capable of articulating this unified doctrine.

Some 40 years after Vivekananda’s journey to the United States, another teacher from India, Paramahansa Yogananda (1893–1952), founded the Self-Realization Fellowship in Los Angeles and introduced the practice and philosophy of Yoga to Americans. Drawing on traditional Hindu teachings of spiritual, mental, and physical discipline, Yogananda represented Yoga in quasi-scientific terms that appealed to his audience, maintaining that other religious teachers (including Jesus and Paul) had also preached much the same message.

It was not until the 1960s and ’70s, however, that NRMs based on Eastern religions became attractive to large numbers of Americans and Europeans. In 1959 Maharishi Mahesh Yogi (1911–2008) founded the Spiritual Regeneration Movement and popularized the technique known as Transcendental Meditation or TM. Transcendental Meditation was also represented as a “scientific” method for obtaining both personal and social peace and harmony; it centred on the repetition of and concentration on an individualized mantra imparted to the initiate by the guru. The Maharishi and his teachings gained great fame and attracted celebrities such as the American film star Mia Farrow, the American engineer and architect R. Buckminster Fuller, and the English rock group the Beatles.

Another group to come out of this period of cultural turmoil and change was the International Society for Krishna Consciousness (ISKCON), founded by A.C. Bhaktivedanta (1896–1977) and popularly known as the Hare Krishna movement. ISKCON is fundamentally a continuation of a Hindu sect, originating in India’s precolonial period, that emphasizes ecstatic devotion to the god Krishna. Conversion to ISKCON entails not only a shift in religious belief and practice but an entire break with Western culture, symbolized by the adoption of Indian dress and diet and by the shaving of male followers’ heads. Such radical signs of alienation from Western culture and values, together with the group’s active proselytizing dimension and its internal crises and leadership struggles, engendered much controversy about the Hare Krishnas.

The Rajneesh International Foundation is another highly controversial NRM that originated in India. The group was led by the flamboyant Bhagwan Shree Rajneesh (1931–90), who taught a heavily revised form of Indian spirituality called Tantrism. Rajneesh urged his Western followers to overcome their repressions through a technique he dubbed “dynamic meditation,” entailing shouting, screaming, and dancing. Rajneesh thus adapted and repackaged ancient Tantric techniques for a Western audience more familiar with psychotherapy.

ISKCON and other imports from the East, such as movements representing Zen Buddhism and the various schools of Tibetan Buddhism, have been introduced into the United States and Europe with little or no alterations to their traditional forms. Their appeal to Westerners may very well lie in their exotic nature and their clear-cut differences from Western religions. Many other Asian traditions, however, have been highly modified by their new contexts or have provided the foundation for the beliefs and practices of Western groups such as ECKANKAR. Especially noteworthy is the emphasis many Eastern-based NRMs place on religious Universalism (a response to pluralism) and on the “scientific” nature of the spiritual teachings and techniques put forward.
