Explanation:

Mage Porob is the principal festival celebrated among the Ho people of eastern India, and is also celebrated by the Munda people, though followers of Birsa Dharam, a new religion based on traditional Munda spirituality and religion, do not celebrate Mage Porob, despite the fact that they celebrate other traditional Munda festivals. It is also not celebrated by any other Munda-speaking peoples, and is much less prominent to the Mundas than to the Hos. It is held in the month of Magha in honor of the deity Singbonga who, in the Ho creation myth, created Luku Kola, the first man on Earth. It was first described in 1912 by Indian anthropologist Rai Bahadur Sarat Chandra Roy in his The Mundas and their Country.
