Definition
Ṛta is the most ancient Indo-Aryan concept of cosmic order, predating and underlying the later concept of dharma. In the Rig Veda, ṛta is the universal principle that maintains the regularity of nature — the rising of the sun, the flowing of rivers, the changing of seasons, the movement of stars. It is the truth that holds the cosmos together. Ṛta is both a natural and moral law: it governs both the physical universe and the moral order. The gods themselves are born of ṛta and uphold it. Varuna is the primary guardian of ṛta. When humans act in accordance with ṛta, they maintain cosmic harmony; when they violate it, they create disorder (anṛta). Ṛta is the precursor to dharma — while dharma is more specific to human duty and social order, ṛta is the universal, pre-personal principle of order.
Etymology
From the Proto-Indo-European root *h₂r̥tós, meaning "fitting, joined, ordered." Related to the Greek arariskein ("to fit") and the Latin artus ("joint"). Ṛta is that which is "properly joined" — the right order of things.

Vedic tradition
Ṛta is the supreme cosmic principle — the order that sustains the universe. Varuna and Mitra are its primary guardians. Sacrifice (yajna) maintains ṛta.
Later Hinduism
Ṛta evolves into the concept of dharma — the moral and social order. The cosmic dimension of ṛta is absorbed into the concept of Brahman as the ground of all order.
Zoroastrianism
The cognate concept is Asha (Avestan: aša) — the divine order and truth. Asha Vahishta is the Best Truth, one of the Amesha Spentas.
