Once Guru Nanak went on a long walk with all his dicsiples. As they were walking some people found money on the ground and they went home. After a long, long distance only two Sikhs were left. Guru Nanak told them to eat a dead body. One Sikh couldn't do it, but Bhai Lehna humbly obeyed. Lehna's devotion surpassed all tests. He was so devoted he was like an 'ang' a limb of the Guru.
