In some contexts, adds White, the term "yogi" has also been a pejorative term used in medieval India for a Nath siddha, particularly on the part of India's social, cultural and religious elites. The term "siddha" has become a broad sectarian appellation, applying to Saiva-devotees in the Deccan ("Maheśvara siddhas"), alchemists in Tamil Nadu ("siddhars" or "sittars"), a group of early Buddhist tantrikas from Bengal ("mahasiddhas", "siddhacaryas"), the alchemists of medieval India ("rasa siddha"), and a mainly north Indian group known as the "Nath siddhas". The Nath siddhas are the only still existing representatives of the medieval Tantric tradition, which had disappeared due to its excesses. While the Nath siddhas enjoyed persistent popular success, they attracted the scorn of the elite classes.
