Guru Nanak Dev Ji selected Bhai Lehna Ji for Guruship due to his devotion and obedience on September 7th, 1539. Bhai Lehna Ji was named Guru Angad Dev Ji. Being the second Guru of the Sikhs Guru Angad Dev Ji was born at Mate Di Sarai in Punjab on March 31, 1504. His father Pheru Mal Ji was a trader. His original name was Lehna. He was married to Mata Khivi Ji. He had two sons, Datu and Dasu. Bibi Amro Ji was his daughter.
Bhai Lehna Ji heard the hymns of Asa Di Var and was fascinated by the teachings of Guru Nanak Dev Ji. He met Guru Nanak Dev Ji at Kartarpur and thereafter remained in Guru’s service for about thirteen years. Upon meeting Guru Nanak Dev Ji, he realised that idols held no meaning in life. His love of the Guru inspired him to become a perfect disciple of the Guru.
Besides maintaining and upholding the traditions laid forth by Guru Nanak Dev Ji, the second Guru created the Gurmukhi script, a medium through which the writings and teachings of the Sikh gurus could be readily understood by their followers. By disassociating the Sikh tradition from Sanskrit influence, a script and language largely unknown to the masses, the Guru emphasised the widespread accessibility of Sikh religious thought. Moreover, it solidified the idea that Sikhism started as a distinct and revealed religion.
Guru Angad Dev Ji made extensive efforts to spread teachings of Guru Nanak Dev Ji far and wide. He improved literacy among the Sikhs and started a school at Khadur Sahib to teach Gurmukhi to the children. He encouraged physical health through sports and wrestling and mental health through discipline and truthful living.
He consolidated the institution of Langar started by Guru Nanak Dev Ji. He encouraged the Sikhs to do selfless service to the human race and surrender to the Will of God. Guru Angad Dev Ji was full of humility, wisdom and generosity. His wife Mata Khivi Ji was known to serve the Sangat in Langar.
Guru Angad Dev Ji excluded his sons and bestowed Guruship on Guru Amar Das Ji. He left for heavenly abode at Khadur Sahib on March 29th, 1552.
