Gurudwara Panjokhra Sahib near Ambala is a major historic gurdwara marking the site where Guru Harkrishan, the eighth Sikh Guru, stayed in February 1664 during his journey from Kiratpur to Delhi at the summons of Emperor Aurangzeb. It was here that the young Guru confounded a proud Brahmin scholar named Krishan Lal by having an illiterate water-carrier named Chhajju deliver a learned discourse on the Bhagavad Gita, demonstrating that divine wisdom transcends worldly learning. An annual fair held during Magh Sudi commemorates the Guru's stay, drawing large sangats from across the region.
