[Query] You mention that there are only three sampradayas in sreevidya and there is no dattatreya sampradaya. None of the tantras mention the three sampradayas. Can you please quote the source. Please clarify is Kali purvanga or uttaranga of sreevidya?

Dakshinamurti: "This is the great Srividya of Tripurasundari consisting of three kUTas or groups of letters, that grants all desires. She [Srividya or Sridevi due to abheda between vidyA and devatA] is described as the queen of all mantras [rAjarAjeshwarI] and as the mistress of the world [jagadIshwarI or tribhuvaneshwarI – again these are equally applicable to vidyA and devatA. The world and its inhabitants are represented by the three bhuvaneshwarI bIjas, described as kUTa makuTas, signifying the three activities of srShTi - sthiti - laya [tirodhAna+anugraha] and the three states of jAgR^it - swapna - suShupti. The nAda emanating from these three mukuTas attain laya in the nAda of the turIya kUTa, represented by tri-bhuvaneshwari]. As a side note, statements glorifying Srividya should not always be treated as arthavAda. vidhi and niShedha are applicable to Tantras as well, as Tantras find their origin in dharma shastras.

kAlii upAsanA as a part of shrIvidyA is again based on sampradAya. For most dAkShiNAtya sampradayas, kAli is not a direct anga vidyA but one of the mantras belonging to uttarAmnAya. However, auttareya sampradayas user kAlii as one of the chief uttarangas of shrIvidyA, the pramANa being bhairavI tantra and tripurasundarI tantra. In this anganavaka scheme, guru chatuShTaya, gaNapati and bAlA are pUrvAngas and annapUrNA, bhuvaneshwarI, dakShiNA kAlii [durvAsa praNItA], rAjashyAmalA, mahAvArAhI and devI hR^idaya vidyA are the uttarAngas. Some think that this scheme applies to sAdi vidyA but that does not seem to be true due to two reasons. One, due to lack of pramANa in these tantras which do not even mention sAdi vidyA. Two, the uddhAra is of kAdi vidyA in these tantras.
