What is Hinduism? Beliefs, texts and practice, explained

Hinduism is the family of religious traditions that grew up in South Asia over more than 3,000 years, with roots in the Vedas, India's oldest scriptures, and no single founder, creed or central authority. What holds it together is that most Hindus share a set of ideas, dharma, karma, rebirth and liberation, revere the Vedas, and often understand their many gods as forms of one ultimate reality. With about 1.2 billion followers in 2020, by Pew Research Center's estimate, it is the world's third-largest religion.

In short

• Hinduism has no founder or fixed creed; many Hindus call it Sanatana Dharma, the eternal way, and it includes a great range of belief and practice.
• Its core ideas are dharma (right duty), karma (action and its results), samsara (the cycle of rebirth) and moksha (release from that cycle).
• Its many gods are often understood as forms of one reality, Brahman, and most Hindus belong to one of four broad traditions or none in particular.

Why is Hinduism hard to define?

Hinduism is unlike religions that begin with one person or one book. The word itself came from outside. Persians and later Greeks named the land and its people after the Indus River, Sindhu in Sanskrit. "Hindu" as a word people used of themselves probably dates to the 15th and 16th centuries, to tell themselves apart from Muslims, and the "ism" was added only in the 19th century, under British rule, the BBC's overview explains.

So there is no test of belief every Hindu must pass. Some Hindus worship a personal God; others think of the ultimate as impersonal. Some define the tradition by the Vedas' authority; others by a way of life. Karma and rebirth are shared with Buddhism, Jainism and Sikhism, so they don't mark Hinduism off on their own. What holds it together is a family of overlapping practices, texts and ideas, the kind of case that makes defining religion hard in the first place.

What do Hindus believe?

Six ideas recur across most Hindu traditions. Each is easier to grasp with an ordinary example.

Idea	What it means	An everyday picture
Dharma	Right duty and the moral order of things; it differs with a person's stage of life and role	A parent's dharma includes caring for children; a judge's, ruling fairly
Karma	Action, and the results it brings, in this life or a later one	Speaking cruelly sows ill will that comes back; a kindness has effects long after
Samsara	The cycle of birth, death and rebirth that a self passes through	Like changing clothes: the body wears out, the self takes another
Moksha	Liberation from samsara, the highest goal	Waking from a long dream and no longer being caught in it
Brahman	The ultimate reality behind and within everything	The ocean beneath every wave
Atman	The true self in each living being	What stays when the roles, the body and the moods change

The "changing clothes" picture comes from the Bhagavad Gita (2.22), which compares the self leaving a worn-out body to a person putting off old garments for new ones. How atman and Brahman relate is one of the great questions of Hindu philosophy. The Advaita Vedanta school, taught by Shankara around the 8th century, holds that they are identical, so that liberation is realizing the self was never separate, as the Internet Encyclopedia of Philosophy explains. Other schools, such as Madhva's Dvaita, hold that the soul and God are eternally distinct.

Classical texts also list four aims of a good life: dharma, artha (prosperity), kama (pleasure and love) and moksha. Wealth and pleasure are not sins; they are proper aims, pursued within dharma.

Do Hindus believe in many gods or one?

Both answers can be heard, and many Hindus would say the question misunderstands the tradition. A verse of the Rigveda (1.164.46) puts it in one line: "Truth is one; the wise call it by many names." Hindus worship many deities, among them Vishnu and his incarnations Rama and Krishna, Shiva, the goddess Devi in forms such as Durga and Lakshmi, and the elephant-headed Ganesha. Many see these as forms or faces of the one Brahman, and a worshipper may devote themselves to one god as supreme while honoring others.

What are the main Hindu texts?

Hindus divide scripture into shruti, "what was heard", revealed truth, and smriti, "what was remembered", texts by human authors. Their dates are approximate and argued; this is a common scholarly outline, and most of these texts are in Sanskrit:

Approximate date	Text	What it is
c. 1500–1200 BCE	Rigveda	The oldest of the four Vedas: hymns to gods such as Agni and Indra, passed down by memory for centuries
c. 1200–800 BCE	Other Vedas and Brahmanas	Chants, ritual formulas and explanations of sacrifice
c. 800–200 BCE	Principal Upanishads	Philosophical dialogues on Brahman, atman and liberation; "you are that"
c. 400 BCE–400 CE	Mahabharata and Ramayana	The two great epics, of a dynastic war and of Rama's exile and return
c. 2nd century BCE–2nd century CE	Bhagavad Gita	Krishna's teaching to the warrior Arjuna, inside the Mahabharata: three paths to liberation, through action, knowledge and devotion
c. 300–1500 CE	Puranas	Stories of the gods, creation and cosmic time
c. 6th century CE onward	Devotional poetry	The Tamil saints, then poets such as Mirabai and Tulsidas, in regional languages

The Vedas are shruti and the most authoritative in principle, but in daily life many Hindus know the epics, the Gita and the Puranas far better.

What are the main Hindu traditions?

Scholars usually describe four main traditions, sampradayas, though many Hindus don't identify with any one of them. Estimates of their sizes differ.

Tradition	Supreme deity	Notes
Vaishnavism	Vishnu, and his avatars, especially Krishna and Rama	Strong emphasis on devotion, bhakti; includes the Hare Krishna movement
Shaivism	Shiva	Ranges from ascetic yogis to temple worship; strong in South India and Kashmir
Shaktism	The Goddess, Devi or Shakti, as Durga, Kali and others	Sees the divine as feminine power; strong in Bengal and Assam
Smartism	Several deities worshipped together, often five	Linked with Shankara and Advaita; the deities are seen as forms of one Brahman

What do Hindus do?

Practice matters more than doctrine to many Hindus. Daily worship, puja, at a home shrine or a temple offers flowers, food, light and incense to an image of a deity, which many worshippers treat as a real presence of the god. Life is marked by rites of passage, samskaras, from naming a child to marriage and cremation. Festivals such as Diwali, the festival of lights, and Holi, the festival of colors, are celebrated across the world, and pilgrimage draws millions to places such as Varanasi on the Ganges. Many Hindus are vegetarian, and the cow is widely revered, though practice varies by region and community. Yoga and meditation grew up in ancient India, in Hindu traditions as well as Buddhist and Jain ones, where they were paths to liberation long before they were exercise.

About 95% of the world's Hindus live in India, and 97% in India and Nepal together, according to Pew Research Center's 2025 report.

What about caste?

Caste is part of Hinduism's social history, and how far it belongs to the religion itself is disputed by Hindus and scholars alike. Ancient texts describe four varnas, priests (Brahmins), rulers and warriors (Kshatriyas), merchants (Vaishyas) and laborers (Shudras), and a hymn of the Rigveda pictures them as parts of a cosmic person. In practice, Indian society was organized into thousands of birth groups called jatis, with rules about marriage, food and occupation, and groups placed outside the system, now called Dalits, faced untouchability. Reformers within and outside Hinduism have challenged it for centuries, from devotional poets who rejected caste rank before God to the Dalit leader B. R. Ambedkar, who chaired the committee that drafted India's constitution. That constitution, in force since 1950, abolished untouchability. Many Hindus regard caste as a social system that grew up around the tradition, not a teaching of it. Buddhism and Sikhism, which also arose in India, rejected caste rank in their teachings.
