Maghi is one of the three festivals chosen by Guru Amar Das Ji to be celebrated by Sikhs (the others being Baisakhi and Diwali).
The Sri Guru Granth Sahib states about the month of Magh:
People take baths on the first day of Magh; you should take the bath of service of the guru; in holy congregation remember God’s virtues, listen and give discourse of them to all...
Accordingly, during the month Magh the “Sikh’s cleansing bath should be the dust of saintly congregation (sadh sangat)”...
Sikhs observe Maghi to honour the heroic fight of the Chali Mukte (Forty Liberated Ones) who gave their lives defending Guru Gobind Singh from an imperial army near Khidrane di Dhab in December 1705.
A large fair is held on Maghi in Muktsar, commemorating the battle site of the Chali Mukte. Pilgrims believe bathing in the pool at Muktsar brings salvation.
This festival celebrates the birth of the tenth Sikh Guru, Guru Gobind Singh Ji. It is widely celebrated with reverence and joy across the Sikh world.
