We have to be thankful to Shankaracharya because Sanatana Dharma, the all-encompassing eternal code of life contained in the Vedas, still flows as the dynamic force underlying and unifying popular Hinduism. It is a monumental testimony to his life and works that this remains so.
The very fact that Hinduism is still a dynamic and all-encompassing religion stands as ample testimony to the deeds of Adi Shankaracharya.
One of His invaluable contributions towards this, after the Bhashya — commentary of Bhagavad Gita, Upanishad & Brahmasutra –, was the reordering and restructuring of the ancient Sannyasa order.
During his travels across the length and breadth of India, he established four maths (ashrams) to unify the scattered and diverse groups of Sannyasis. These four maths were established, about 700 BCE, in four different corners of India. He selected four of his senior-most disciples to head each of these maths. Each of these maths was assigned the task of maintaining and preserving for posterity, one of the four Vedas
Shankaracharya reorganised all the Sannyasis in India into ten main groups known as the Dasanami Tradition*. These orders are also allocated to different maths.
Historical and literary evidence also exist which prove that the Kanchi Kamakoti Mutt at Kancheepuram, in Tamil Nadu, was also founded by Shankaracharya.
