Gurudwara Gurubagh Sahib in Varanasi marks the visit of Guru Nanak Dev Ji during his first Udasi in 1507. Guru Ji rested in a garden here, where he shared spiritual wisdom and transformed lives, including those of Pandit Gopal Shastri, Chatur Das and a cursed priest named Ganga Ram. The garden became sacred and the site is now a revered Gurudwara.
