The festival day for brothers.
When Raja Nandivardhan, the brother of Shraman Bhagawan Mahavir was steeped in sorrow and anguish on account of the latter’s nirvan (attainment of Mukti) his sister, Sudarshana took him to her house and comforted him. This happened on the second day of the fortnight of the waxing moon, in Kartik. This day is observed as Bhai Beej. This festival is like Raksha Bandhan. On the day of Rakshabandhan, the sister goes to the brother and ties the Raksha; but on this day, the sister invites her brother to her house to felicitate him.
