Dharma (Sanskrit: धर्म dhárma, Pali: धम्म dhamma; lit. that which upholds or supports) means Law or Natural Law (as in the natural order of things) and is a concept of central importance in Indian philosophy and religion. In the context of Hinduism, it refers to one's personal obligations, calling and duties, and a Hindu's dharma is affected by the person's age, caste, class, occupation, and gender. In modern Indian languages it can refer simply to a person's religion, depending on the context.
The idea of dharma as duty or propriety derives from an idea found in India's ancient legal and religious texts that there is a divinely instituted natural order of things (rta) and justice, social harmony and human happiness require that human beings discern and live in a manner appropriate to the requirements of that order. According to the various Indian religions, such as Hinduism, Jainism, Buddhism, and Sikhism, beings that live in accordance with dharma proceed more quickly toward dharma yukam, moksha or nirvana (personal liberation). See Dharma (Buddhism).
In traditional Hindu society, dharma has historically denoted a variety of ideas, such as Vedic ritual, ethical conduct, caste rules, and civil and criminal law. Its most common meaning however pertains to two principal ideals: that social life should be structured through well-defined and well-regulated classes (varna), and that an individual's life within a class should be organized into defined stages (ashrama, see dharmasastra).
In the Rigveda, the word appears as an n-stem, dhárman-, with a range of meanings encompassing "something established or firm" (in the literal sense of prods or poles), figuratively "sustainer, supporter" (of deities), and semantically similar to the Greek ethos ("fixed decree, statute, law"). In Classical Sanskrit, the noun becomes thematic, dharma-.
It is a derivation from Proto-Indo-Iranian root *dhar- ("to fasten, to support, to hold"), in turn reflecting Proto-Indo-European root *dʰer- ("to hold"), which in Sanskrit is reflected as class-1 root √dhṛ. Etymologically it is related to Avestan √dar- ("to hold"), Old Persian √dar- ("to hold, have"), Latin frēnum ("rein, horse tack"), Lithuanian derė́ti ("to be suited, fit"), Lithuanian dermė (agreement), darna ("harmony") and OCS drъžati ("to hold, possess"). Classical Sanskrit word dharmas would formally match with Latin o-stem firmus < *PIE *dʰer-mo-s "holding", were it not for its historical development from earlier Rigvedic n-stem.
From the Atharvaveda and in Classical Sanskrit, the stem is thematic, dhárma- (Devanāgarī: धर्म), and in Pāli, it takes the form dhamma. It is also often rendered dharam in contemporary Indian languages and dialects. It is used in most or all philosophies and religions of Indian origin—sometimes summarized under the umbrella term of Dharmic faiths—including Hinduism, Buddhism, Jainism, and Sikhism. It is difficult to provide a single concise definition for dharma, as the word has a long and varied history and straddles a complex set of meanings and interpretations.
Hinduism, Buddhism, Jainism, and Sikhism are called Hindu Dharma, Buddha-Dharma, Jain-Dharma and Sikh dharma, respectively.
