 Although this meaning is not actually cited by authoritative Sanskrit dictionaries it is a regular derivation from the verbal root ṛ, “to move” with ta, the suffix which forms the past participle, so it can be regarded as the putative origin of the word.More abstractly, it is translated as "universal law" or "cosmic order", or simply as "truth".The latter meaning dominates in the Avestan cognate to "Ṛta", "aṣ̌a".
