 The term appears in Vedic texts and in post-Vedic texts, both as Ṛta and derivatives of the term.For example, in the 2nd-century BCE text "Mahabhasya" of Patanjali, he explains "Ṛtaka" to be the grammatically correct form of name for a son, where then the name would mean "truthling".In scholarship there is no common position about the origin of the concept of "Ṛta".
