Kalashtami is a festival that falls on the eighth day of the second half of the month of Kartik. The legend is that on this day angry Kala Bhairav, a creation of Lord Shiva
, chopped off one of the five heads of Lord Brahma
and proceeded to Benares
. Since the presiding deity of Benares is Kala Bhairav, the devotees throng here to celebrate this day by fasting and prayers.
