The Sharada math, Shringeri math, and Govardhan math are the
other three maths(mutts) or holy places said to have been built by the renowned
scholar Shankaracharya.
The Jyotir math located in the northern quarter, in the town
of Joshimath in the state of Uttar Pradesh, high in the Himalaya Mountains, and
is related with one of the four geographical corners of the Indian
subcontinent.
The Dashanami Sanyasis, the most prominent Hindu ascetic
order, is said to have been founded by Shankaracharya.
The Dashanami ("ten names") ascetics are Shiva's
worshippers (bhakta) who are divided into 10 divisions, each with its own name.
The 10 divisions are divided into four groups: Anandawara,
Bhogawara, Bhuriwara, and Kitawara, each of which contains two or three of the
ten divisions and is linked to one of the four holy centers.
The Anandawara group of the Dashanamis is related with the Jyotir math.
