I just want to give a clear picture about what are the origins of the Ahobila mutt. It is a religious institution formed at the end of the 14th century by Srimad Aadivan Satakopa Yateendra mahadesika. He was born in the year 1379 in the prestigious Athreya gothra to a great scholar who lived in Thirunarayanapuram (Melkote) called Keshavachar. He was named Srinivasa and underwent the samasrayana under his father who hails from the parampara where after Ramanuja.
The following chain of acharya could be seen: Embar-Bhattar-Nanjeeyar-Nampillai-VadakkuThiruveethiPillai-Srirangachar (father of the great grandfather of adivan satkopa)-his son Keshavachar-his son Srinivasachar-his son Kesavachar (who is the father and samasrayanaacharya of adivan satakopa).
At this point you should note that the parampara is the same as the parampara of swami manavala mamunigal (who himself got the preshamanthropadesha, a mantra for initiating into the sanyasashrma, from adivan satakopa).
Sri rangachar who is a distan relative of swami desika's guru kidambi Appular, followed the vadakala tradition. But he got his samasrayanam under vadakku Thiruveethipillai, since it is his choice as to whom to opt as his acharya and also there were no differences in sects till 17th century.
Therefore it cannot be taken that adivan satakopa swamy was a thenkalai and that he changed to vadakalai. Then he was sent study higher adhyatmic studies under ghatikasatham ammal, who hails from the lineage of vedanta desika, therefore having desika in his kalakshepa parampara. Then at the age of 21 he renounced all materialistic practices and got sanyasa from Lord Narasimha of the Ahobila Himself. Then on started the holy monastic organization under the order of swamy lakshmi narasimha and srimad aadi van satakopa yateendra mahadesika which follows the vadakali sect.
Unlike one said that ahobila mutt has attachments with both the sects, the ahobila mutt has more authority in the vadakalai sect. But there are inscriptions that all descendants of the 74 simhasanadhipathis approached swami for acharyathvam. I also want to mention something here is that vadakalai sect is not a lately formed sect as it existed even when thenkalai sect started. Therefore any confusions regarding this are severely misleading thank yo
