Viveka is a Sanskrit term that is sometimes translated as discernment or, in its more favorable sense, discrimination. According to Rao and Paranjpe, viveka can be explained more fully as:
Sense of discrimination; wisdom; discrimination between the real and the unreal, between the self and the non-self, between the permanent and the impermanent; discriminative inquiry; right intuitive discrimination; ever present discrimination between the transient and the permanent.
Viveka is the basis of the monastic name of Swami Vivekananda, the first Hindu spiritual teacher to journey to the west.
