Guru Angad (1504-1552) was born Bhai Lehna, a merchant of Khadur who, before he met Guru Nanak, was a devotee of the goddess Durga and led pilgrim parties to her shrine. His encounter with Nanak turned his life, and Nanak in time chose him over his own sons, Sri Chand and Lakhmi Das, renaming him Angad, from ang, "limb", to mark him as part of the Guru's own body.
The choice was deliberate and, in the tradition's telling, tested. Sikh accounts relate a series of trials of obedience and humility that Lehna passed while Nanak's sons hesitated, and the succession that resulted set a lasting principle for the young community: the office of Guru passes to the worthiest disciple, not by blood. That pattern held, with one shift, for a further eight Gurus.
Installed in 1539, Angad settled not at Nanak's Kartarpur but at Khadur Sahib, establishing a distinct centre. Historians treat the bare facts of his succession and location as secure, while noting that much of the surrounding narrative comes from the later janamsakhi and gur-bilas literature and carries the shape of hagiography.
