Nanak's successor and thus the second guru.

Guru (Ministry 1538-53)—Second in succession to Nanak, original name being Bhai Lehna. Nanak recognised in him his worthy successor, with a claim to his spiritual riches (Lehna), in preference to his own sons. Nanak styled him 'Angad,' i.e., one cast in his own mould and filled by his own light, as a veritable part of his own being.
