In the hinduist religion and indian philosophy is crucial and continuously flashing the concept of Ṛta ऋतं, the cosmic order , the order which coordinates the universe splits in its two components of natural and moral order. Ṛta is derived from the Sanskrit verb root ṛ- « to go, move, rise, tend upwards », and the derivative noun ṛtam is defined as « fixed or settled order, rule, divine law or truth ».
If Satya (सत्य | truth) is the law, then Rta is the order which implements the law. It is equated with and considered necessary to Ṛta: it results from Satya as it regulates and enables the operation of the universe and everything within it. Satya is considered essential, and without it, the universe and reality falls apart, cannot function.
