Guru Amar Das, sometimes spelled as Guru Amardas, was the third guru of Sikhism and became Sikh Guru on 26 March 1552 at age 73.
Before becoming a Sikh (Shishya from Sanskrit), on a pilgrimage after having been prompted to search for a guru, he heard his nephew's wife, Bibi Amro, reciting a hymn by Guru Nanak, and was deeply moved by it. Amro was the daughter of Guru Angad, the second Guru of the Sikhs. Amar Das persuaded Amro to introduce him to her father. In 1539, Amar Das, at the age of sixty, met Guru Angad and became a Sikh, devoting himself to the Guru.
