Explanation:

 Guru Angad Dev ji, Nanak II, was the second of the ten human form Gurus (divine messengers) of the Sikh faith.

Guru ji was born with birth name Lehna in the year 1504 at Harike, Amritsar, Punjab, to father Bhai Pheru Mall Ji and mother Mata Sabhrai Ji (also known Daya Kaur). Born in a Hindu family, Bhai Lehna ji used to be a worshipper of the Hindu Goddess Durga. At age 27, after hearing the recitation of hymns of Guru Nanak from Bhai Jodha (a Sikh of Guru Nanak), Bhai Lehna decided to travel to Kartarpur to meet the Guru. Having met Guru Nanak only once, Bhai Lehna was transformed to such an extent that he decided to renounce his own faith and became a Sikh of Guru Nanak, devoting himself completely to Guru Nanak and his mission. His discipleship was subjected to various tests by Guru Nanak himself, following which he came to be renowned as an embodiment of obedience and service to the Guru and humanity. Before passing away, Guru Nanak renamed Bhai Lehna as Angad (from Ang, or one's own body part), and installed him as his successor, the second Nanak, on 13 June 1539.
