In the timeperiod after the vedic area master Adi Shankara introduced the Advaity Vedanta sampradaya. He divided india into four areas - each with a Shankaracharya.
A visit to the Shankaracharya (TM-EX-Letter of Robert Kropinski from the internet) :
Since the 80ies the Shankara-Order does not accept Maharishi and rejects him. Maharishi was only the secretary of Guru Dev and a sadhu and not a initiated disciple. Guru Dev, who died from poison, had wanted two other persons as successor, and there is no proof that Guru Dev was a fully enlightened master (Unity).
Maharishis teachings inclusive the Transcendental Meditation and the siddhis are very different from the traditional Advaita-Vedanta -Teachings of the Shankara-Order, and he does not represent the "Holy tradition" (and i am fully convinced that he is a black master or Rudra-master !).
The (alleged) siddhis are in claring contradiction to the teachings of the order, and even Pantanjali warns before them.
* Wiki : TM-History
At the beginning of the nineties Maharishi moved the Guru Dev somewhat into the background and turned to Veda, which Shankara had once superseeded with 'Advaita' because of the many errors which had crept into traditional Veda, and to Ayurveda and Siddhis like doubtful yogic "flying"(Superfoam hopping), 'peace'- palaces and ' invincibility'(-towers)...
At the 6. February 2008 Maharishi died - after he had said he had met Guru Devs alleged mission.
Since then is Maharaja Adhiraj Rajaraam Tony Nader president[who had received his weight in gold].
