Guru Gobind Singh and his Khalsa, a defense militia of “soldier-saints” he formed, were attacked by the Mughal army at Anandpur. It is said that 40 of his close followers joined the Guru at Muktsar, where they gave their lives in the Battle of Muktsar in December 1705. Maghi is a day for honoring these men, who are now known as the Forty Immortals. Sikhs in India and elsewhere observe the holiday by visiting their local gurdwara (house of worship) and listening to the recitation of sacred hymns. The observance is particularly solemn at Muktsar, where the slaughter occurred. Discuss
