Aurangzeb summoned Guru Hari Krishen (1656–64) to Delhi from the Shiwalik Hills. While in Delhi, Hari Krishen contracted smallpox, which proved fatal. Before he died, he uttered the words “Baba Bakale,” which indicated to his followers the identity of his successor, the baba (“old man”) who is in the village of Bakala. Hari Krishen meant to identify Tegh Bahadur, who dwelt in Bakala and was the son of Guru Hargobind by his second wife and the half brother of Guru Hari Krishen’s grandfather.
