Ahmadiyya — The Way of the Promised Messiah — An ethnographic introduction to the Ahmadiyya Muslim Community — the messianic Islamic reform movement founded by Mirza Ghulam Ahmad in Qadian, Punjab, in 1889, now comprising ten to twenty million adherents in over two hundred countries, led by a living caliph, and constituting one of the most systematically persecuted religious communities on Earth, declared non-Muslim by the Pakistani state in 1974 and subject to blasphemy laws that criminalise the practice of their faith.
Ananda Marga — The Path of Bliss — An ethnographic introduction to Ananda Marga Pracaraka Samgha (आनन्दमार्ग प्रचारक संघ) — the spiritual and social movement founded in 1955 by Prabhat Ranjan Sarkar (Shrii Shrii Anandamurti, 1921–1990) in Jamalpur, Bihar, which combines tantric meditation, a neo-humanist philosophy that extends ethical concern to all living beings, and a radical socio-economic theory (PROUT — Progressive Utilization Theory) into a comprehensive system of individual transformation and social revolution — operating in over 180 countries with monastics, lay practitioners, schools, disaster relief operations, and a vision of a spiritualized society.
Arya Samaj — The Society of the Noble — An ethnographic introduction to the Arya Samaj, the Hindu reform movement founded in Bombay in 1875 by Swami Dayananda Sarasvati — a Gujarati ascetic who argued that all idolatry, priestly mediation, and caste discrimination were corruptions of a primordial Vedic monotheism available to every human being regardless of birth, sex, or sect. Simultaneously the most conservative and the most radical of the Indian Aquarian movements, the Arya Samaj built more schools than any other modern Indian religious organization, introduced proselytism into Hinduism for the first time, and supplied the intellectual DNA for both the Indian independence movement and, in its darker tendency, for Hindu nationalism.
Ayyavazhi — The Way of the Father — An ethnographic introduction to Ayyavazhi (ஐயாவழி), the Tamil monotheistic religion founded through the life and revelations of Ayya Vaikundar — a movement of radical caste-abolition, direct divine encounter, and eschatological hope that emerged in 1833 from the impoverished fishing villages of South Travancore and became one of the most theologically distinctive religious movements of the nineteenth century.
BAPS Swaminarayan Sanstha — An ethnographic introduction to BAPS Swaminarayan Sanstha (Bochasanwasi Akshar Purushottam Swaminarayan Sanstha), the Gujarat-rooted Hindu new religious movement founded in 1907 on the conviction that God's presence continues in the world through an unbroken lineage of living human manifestations — the Akshar — and that devotion to this living Akshar is the surest path to liberation. With over 1,300 temples across 45 countries and the largest Hindu temple outside Asia opened in Robbinsville, New Jersey in 2023, BAPS is among the most architecturally visible and organizationally sophisticated of the Aquarian communities.
Baul Tradition — The Way of the Maner Manush — An ethnographic introduction to the Baul tradition of Bengal — the lineage of wandering mystic-singers who rejected caste, scripture, temple, and mosque in favor of direct encounter with the maner manush, the divine man of the heart, through song, body practice, and the living guru-disciple transmission.
Brahma Kumaris — The Way of Raja Yoga — An ethnographic introduction to the Brahma Kumaris (ब्रह्माकुमारी) — the Raja Yoga meditation movement founded in 1937 by Dada Lekhraj in Hyderabad, Sindh, which teaches that God is Shiva, a dimensionless point of light; that the soul cycles through five world-ages of 1,250 years each in an eternally repeating kalpa; that liberation comes through Raja Yoga meditation and the cultivation of soul-consciousness — and which has grown, under almost entirely female leadership, into one of the largest spiritual organizations in the world, with over 8,000 centers in 110 countries.
Brahmo Samaj — The Society of Brahma — An ethnographic introduction to the Brahmo Samaj, the Hindu reform movement founded in Calcutta in 1828 by Ram Mohan Roy — arguably the first organized Aquarian community in the world, predating Emerson's Divinity School Address by a decade. Emerging from a Brahmin polymath's lifelong effort to distill the monotheistic core of the Upanishads from the ritual accretions of popular Hinduism, the Brahmo Samaj gave India its first institutionalized campaign against sati, its first systematic women's education movement, and the intellectual formation of the generation that would produce Rabindranath Tagore and the Indian national awakening.
ISKCON — International Society for Krishna Consciousness — An ethnographic introduction to the International Society for Krishna Consciousness, the Gaudiya Vaishnava movement founded in New York in 1966 by A.C. Bhaktivedanta Swami Prabhupāda, which transplanted the five-hundred-year-old Bengali devotional tradition of Chaitanya Mahāprabhu into the American counterculture and, through an extraordinary decade of expansion, produced both a genuinely global religious presence and some of the most painful institutional failures of the twentieth-century Aquarian movement.
Jainism — The Way of Non-Harm — An ethnographic introduction to Jainism — one of the oldest religions on Earth, founded on the radical principle of ahimsa (non-harm to all living beings), the philosophical doctrine of anekantavada (many-sidedness of truth), and the practice of progressive renunciation toward liberation, with approximately four to five million adherents primarily in India and a growing global diaspora.
Lingayatism — The Way of the Vachana — An ethnographic introduction to Lingayatism (ಲಿಂಗಾಯತ) — the medieval Karnataka tradition founded by Basavanna in the 12th century, which rejected caste hierarchy, priestly intermediaries, and Vedic authority in favor of direct personal union with Shiva, expressed through 21,000 Vachanas (devotional sayings) composed by 259 sharanas including hundreds of women, and organized around the radical egalitarian assembly of the Anubhava Mantapa.
Meher Baba — The Silent Master — An ethnographic introduction to the Meher Baba movement — the spiritual tradition founded by Merwan Sheriar Irani (1894–1969), an Irani Zoroastrian who declared himself the Avatar of the age, maintained complete silence for the last forty-four years of his life, produced one of the most intricate cosmological systems in modern religion (God Speaks), gathered followers across India, America, Europe, and Australia, and left behind a tradition organized not around a successor but around a Beloved who said he would not come again.
Nepali Shamanism — The Way of the Jhankri — A profile of the living shamanic traditions of Nepal — the jhankri, bombo, dhami, and other ritual specialists who drum between the three worlds. Pre-Hindu, Tibeto-Burman in origin, and still widely practiced in the hills and mountains where the Himalayan axis connects Bon above to the earth spirits below.
Radhasoami — The Way of the Sound Current — An ethnographic introduction to the Radhasoami (राधास्वामी) tradition — the Sant meditation movement founded by Soamiji Maharaj in Agra in 1861, which teaches Surat Shabd Yoga (union of the soul with the inner Sound Current), requires a living Master for initiation, maps the soul's ascent through five inner spiritual regions to the nameless Absolute, and has grown through multiple lineages — most prominently the Radha Soami Satsang Beas — into one of the largest meditation-based spiritual movements in the world, with millions of initiated practitioners across six continents.
Ramakrishna Mission — The Order of Practical Vedanta — An ethnographic introduction to the Ramakrishna Mission, the Hindu monastic and humanitarian organization founded in 1897 by Swami Vivekananda in the name of his master Sri Ramakrishna Paramahamsa — a Bengali temple priest whose life of direct mystical experience across Hindu, Islamic, and Christian modes of practice became the basis for neo-Vedanta, the most globally influential systematization of Vedantic universalism in the modern era. The Mission represents the fullest synthesis of the South Asian Hindu reform impulse: it preserves the devotional tradition that the Brahmo Samaj rationalized and the Arya Samaj Vedified, while insisting that service to the poor is the supreme form of worship.
Sahaja Yoga — The Way of Spontaneous Union — An ethnographic introduction to Sahaja Yoga — the global meditation movement founded in 1970 by Nirmala Srivastava (Shri Mataji Nirmala Devi, 1923–2011), built around the claim that kundalini awakening (Self-Realization) is a spontaneous, verifiable event that can be transmitted en masse without years of preparation — producing a worldwide community of practitioners in over 100 countries, free meditation programs, and a distinctive theology that synthesizes Hindu, Christian, and Islamic sacred history into a single evolutionary framework.
Sant Tradition — The Voice That Has No Temple — An ethnographic introduction to the Sant tradition of North India — the lineage of poet-mystics who rejected caste, idol worship, and the authority of both Hindu and Muslim institutions in favor of direct devotion to the formless divine, expressed through vernacular verse that became the foundation of Sikhism and one of the most powerful theological arguments for human equality in medieval India.
Sathya Sai Baba — The Way of the Avatar — An ethnographic introduction to the Sathya Sai Baba movement — the devotional tradition centered on Sathya Narayana Raju (1926–2011) of Puttaparthi, Andhra Pradesh, who declared himself the reincarnation of the Sufi-Hindu saint Shirdi Sai Baba and an avatar of God, attracted millions of followers across six continents, established a vast infrastructure of schools, hospitals, and water projects, and became one of the most venerated and most controversial spiritual figures in modern Indian history.
Self-Realization Fellowship — The Way of Kriya Yoga — An ethnographic introduction to the Self-Realization Fellowship (SRF) — the spiritual organization founded by Paramahansa Yogananda in Los Angeles in 1920, which teaches Kriya Yoga as a scientific method of God-realization, bridges Hindu and Christian mystical traditions, operates through a global network of temples, meditation centers, and a monastic order, and has influenced millions through Yogananda's Autobiography of a Yogi — one of the most widely read spiritual texts of the twentieth century.
Shaiva Siddhanta — The Way of the Lord — An ethnographic introduction to Shaiva Siddhanta (சைவ சித்தாந்தம்) — the ancient Tamil philosophical and devotional tradition that became the most systematic form of Shaivite religion ever developed, and that continues today as a living faith of millions in Tamil Nadu, Sri Lanka, and the global Tamil diaspora, sustained by an unbroken temple tradition, sixty-three poet-saints, and the most beloved corpus of devotional poetry in the Tamil language.
Sikhism — The Way of the Guru — An ethnographic introduction to Sikhism — the world's fifth-largest religion, founded in the Punjab in 1469 by Guru Nanak Dev Ji, whose direct experience of divine unity became the basis for a tradition that rejected caste hierarchy, priesthood, and ritual formalism in favor of direct access to God, selfless communal service, and the householder's path through the world. Sikhism's twenty-five to thirty million adherents are organized around the Guru Granth Sahib — the eternal living scripture installed as Guru in 1708 — and the Khalsa, the community of initiated believers founded in 1699. The Langar, the free communal kitchen at every Gurdwara that serves all comers without distinction of caste, class, religion, or gender, is perhaps the most radical institutionalization of equality in the history of world religion.
Sri Aurobindo Ashram and Auroville — An ethnographic introduction to the Sri Aurobindo Ashram (est. 1926, Pondicherry) and Auroville (est. 1968) — the twin institutions of a tradition that made the most ambitious claim in the history of Aquarian religion: that spiritual practice is not the path to liberation from the world but the instrument of the world's transformation, that matter itself can be divinized, and that the next stage of human evolution is already underway.
Swadhyay Parivar — The Family of Self-Study — A profile of the Swadhyay Parivar, the Bhagavad Gita-based devotional movement founded by Pandurang Shastri Athavale in mid-twentieth-century India — a tradition that turned the Gita's teaching of the indwelling God into a practical social philosophy of collective devotional labor, producing fishing cooperatives as temples, farms as prayer halls, and the simple act of visiting your neighbor as the highest act of worship.
Tamil Siddhars — The Way of the Accomplished One — An ethnographic introduction to the Tamil Siddhar tradition — the lineage of wandering adept-saints who rejected caste hierarchy, temple worship, and Brahminical authority in favor of direct inner transformation through yoga, alchemy, and mystical experience, centered on the Tirumantiram of Tirumular, the foundational philosophical text of Tamil Shaiva spirituality.
The Dalit Buddhist Movement — Navayana — A profile of the Dalit Buddhist movement — the mass conversion initiated by Dr. B.R. Ambedkar on October 14, 1956, when he led roughly 600,000 Dalits in Nagpur to take refuge in the Buddha, rejecting the caste system that had held their ancestors for millennia. Now comprising over fifty million adherents, the movement represents the largest mass conversion in Buddhist history and the most radical reinterpretation of the Pali Canon since Nichiren — a Buddhism without karma as cosmic justice, without rebirth as metaphysical fact, and with the Indian Constitution as its second scripture.
The Nath Tradition — The Way of the Ear-Split Yogis — An ethnographic introduction to the Nath tradition (Natha Sampradaya) — the medieval Indian yogic lineage of Matsyendranath and Gorakhnath that developed Hatha Yoga, transformed Shaiva Tantra into a system of bodily discipline accessible to all castes, and survives today as one of the most important living ascetic orders in South Asia, with monasteries across India and Nepal and a membership that includes the current Chief Minister of Uttar Pradesh.
The Osho Movement — The Way of Zorba the Buddha — An ethnographic introduction to the Osho movement — the global spiritual community founded by Bhagwan Shree Rajneesh (1931–1990), later known as Osho, who taught a radical synthesis of Eastern mysticism and Western psychology centered on meditation, celebration, total acceptance of life, and the destruction of all conditioning — a movement that became the most controversial and arguably the most culturally influential new religious phenomenon of the late twentieth century.
The Warkari Tradition — The Way of the Pilgrim Road — An ethnographic introduction to the Warkari tradition — Maharashtra's great devotional movement centered on the worship of Vithoba at Pandharpur and the annual Vari pilgrimage, sustained by the poetry of Dnyaneshwar, Namdev, Eknath, and Tukaram, and carrying hundreds of thousands of pilgrims on foot across the Deccan plateau every year in one of the largest devotional gatherings on Earth.
Transcendental Meditation — The Maharishi Movement — An ethnographic introduction to the Transcendental Meditation movement — founded by Maharishi Mahesh Yogi in 1955 as a transmission of Advaita Vedanta for the modern world, and built into a global institution encompassing millions of practitioners, an accredited university, a purpose-built city in Iowa, and the most extensively studied meditation technique in the scientific literature. The movement's central paradox: a tradition that presented itself to the world as secular, scientific, and non-religious while teaching Hindu initiation, Vedic mantras, and a complete cosmology of divine consciousness.
