Buxar (Baksar, Urdu: بکسر) is a city in the state of Bihar in the Eastern part of India. It is the headquarters of Buxar District. The word Buxar is said to have been derived from VyaghraSar. The tiger face of Rishi Vedshira, an outcome of the curse of the sage Rishi Durvasa, was restored after bathing in a holy tank which was later named as VyaghraSar.
