The exact origin of the Deusi-Bhailo tradition is not very clear. However, the Deusi and Bhailo songs indicate that this tradition is related to King Mahabali, since the lyrics of the songs says We were sent by King Bali. The word deusurey used in the songs could be a conjunction of two words Dev and Asur. King Mahabali had a mixed Dev and Asur lineage. He was the great grandson of the Asura king Hiranyakshipu, the grandson of Prahlada and the son of Virochana. Also, the word deusire (variation of deusurey) used in the songs could be broken down as deu, which means give in Nepali, and sire, which is the Sanskrit word for head. So deusire could mean to offer one's head for a greater cause or in other words sacrifice oneself. According to the Puranas, King Bali gave his own head to Vamana, the fifth incarnation of Lord Vishnu. King Bali was performing the Ashwamedhya Yajna, when Vamana approached Bali and asked for land that would equal three strides he took. Bali was known for giving alms to any one who came to his palace. Bali agreed to fulfill his demand. To Bali's great surprise, Vamana covered the Earth and the Universe with two steps, and then asked him where he should place his third step. Bali offered his own head. Lord Vishnu, seeing the devotion of Bali, blessed him and raised to him to Suthala, the supreme position in heaven. For his sacrifice, Bali gained Lord Vishnu's favour and also attained salvation.
