Sattriya is a classical dance from the northern state of India called Assam. The dance was created and practiced by monks for many centuries before it emerged out of the monastery to the general population.  Sattriya is derived from the word "Sattra," which is a type of Assamese monastery.  There are two styles of Sattriya -- one  masculine, referred to as Tanday, and the other feminine, called Lasya.  It is one of the eight principal classical dances of India.  Sattriya has sixty four different matikhoras (body postures).
