Sanātana Dharma (Devanagari: सनातन धर्म, meaning "eternal dharma", or "eternal order") is an endonym for certain sects of Hinduism, and used as an alternative term to the exonyms of Hinduism, including Hindu Dharma. The term is found in Sanskrit and other Indian languages. It is generally used to signify a more traditional outlook of Hinduism.
The term denotes the "eternal" or absolute set of duties or religiously ordained practices incumbent upon all Hindus, regardless of class, caste, or sect.
Currently many Hindus in Indian subcontinent call themselves Sanatanis, that is, those who follow the 'eternal dharma', to evoke a certain homogeneity in Hinduism, although it's also sometimes used by Jains and Buddhists who believe in concepts like rebirth. Its use to signify Hinduism as a religion was popularised since 19th century by the champions of Hindu orthodoxy such as Pandit Shraddha Ram in order to react against missionaries and Hindu reformers such as Arya Samaj and Brahmo Samaj. Aside from its use in socio-religious contexts, it also sustains a political necessity for many Hindus to this day.
In Sanskrit, Sanātana Dharma translates approximately to "eternal law" or, less literally, "eternal way." In Pali, the equivalent term is Dhammo Sanātano (धम्मो सनन्तनो). In Hindi, the Sanskrit tatsama dharma (धर्म) is being used as "religion". Sanātana Dharma (सनातन धर्म) roughly translates to "eternal religion".
Dharma is often translated as "duty", "religion" or "religious duty", but has a deeper meaning. The word comes from the Sanskrit root "dhṛ" (धृ) which means "to sustain" or "that which is integral to something" (e.g., dharma of sugar is to be sweet, fire to be hot). A person's dharma consists of duties that sustain them according to their innate characteristics which are both spiritual and material, generating two corresponding types:
According to the notion of sanatana-dharma, the eternal and intrinsic inclination of the living entity (atman) is to perform seva (service). Sanatana-dharma, being transcendental, refers to universal and axiomatic laws that are beyond our temporary belief systems.
The phrase dharma sanātana occurs in classical Sanskrit literature, for example, in the Manusmrti (4-138) (c. 1st – 3rd century CE) and in the Bhagavata Purana (c. 8th – 10th century CE).
In the late 19th century, the term was revived during the Hindu revivalism movement as a name for Hinduism as a religion in order to avoid having to use the exonym "Hindu" which is of non-native Persian origin.
Today, Sanatana Dharma is associated only with Hinduism. In current-day usage, the term sanatana dharma is diminished and used to emphasize a "traditional” or sanatani ("eternalist") outlook in contrast to the socio-political Hinduism embraced by movements such as the Arya Samaj. In sharp contrast to the efforts by Lahore Sanatana Dharma Sabha to preserve the Hindu tradition against the onslaught of reform, now it is being stressed that Sanatana Dharma cannot be rigid, it has to be inclusive without excluding the best and totality of knowledge to guide the karmic process, especially as Sanatana has no beginning and no end.
Sanatanis and reformists (such as the Arya Samaj, the Radha Soamis and the Ramakrishna Mission) have competed for adherents for more than a century, sometimes creating deep schisms in Hindu society, as in the case of South African Hindus who were split between the Arya Samaj and Sanatanis. While the reformist groups were better organized initially, by the 1860s, a process of internal counter-reform was underway in Sanatani groups as well, and societies to propagate orthodox beliefs along modern lines emerged, such as Sanatana Dharma Rakshini Sabha in 1873. Some religious commentators have compared the Sanatani-Samaji dichotomy within Hinduism as similar to the Catholic-Protestant division in Christianity.

Dharma is often translated as "duty," "religion" or "religious duty" and yet its meaning is more profound, defying concise English translation. The word itself comes from the Sanskrit root "dhri," which means "to sustain." Another related meaning is "that which is integral to something." For example, the dharma of sugar is to be sweet and the dharma of fire to be hot. Therefore, a person's dharma consists of duties that sustain them, according to their innate characteristics. Such characteristics are both material and spiritual, generating two corresponding types of dharma:
(a) Sanatana-dharma – duties which take into account the person's spiritual (constitutional) identity as atman and are thus the same for everyone.
(b) Varnashrama-dharma – duties performed according to one's material (conditional) nature and specific to the individual at that particular time (see Varnashrama Dharma).
According to the notion of sanatana-dharma, the eternal and intrinsic inclination of the living entity (atman) is to perform seva (service). Sanatana-dharma, being transcendental, refers to universal and axiomatic laws that are beyond our temporary belief systems. ...
