The founder of the Sikh religion, Guru Nanak was born on April 15, 1469 in the Western Punjab village of Talwandi. He was born to a simple Hindu family. His father Mehta Kalian Das was an accountant in the employment of the local Muslim authorities. From an early age Guru Nanak made friends with both Hindu and Muslim children and was very inquisitive about the meaning of life. At the age of six he was sent to the village school teacher for schooling in reading and writing in Hindi and mathematics. He was then schooled in the study of Muslim literature and learned Persian and Arabic. He was an unusually gifted child who learned quickly and often question his teachers. At age 13 it was time for Guru Nanak to be invested with the sacred thread according to the traditional Hindu custom. At the ceremony which was attended by family and friends and to the disappointment of his family Guru Nanak refused to accept the sacred cotton thread from the Hindu priest. He sang the following poem;

"Let mercy be the cotton, contentment the thread, Continence the knot and truth the twist. O priest! If you have such a thread, Do give it to me. It'll not wear out, nor get soiled, nor burnt, nor lost. Says Nanak, blessed are those who go about wearing such a thread" (Rag Asa)

As a young man herding the family cattle, Guru Nanak would spend long hours absorbed in meditation and in religious discussions with Muslim and Hindu holy men who lived in the forests surrounding the village. Thinking that if bound in marriage Guru Nanak might start taking interest in household affairs a suitable match was found for him. At age 16 he was married to Sulakhani daughter of a pious merchant. Guru Nanak did not object as he felt that married life did not conflict with spiritual pursuits. Guru Nanak was happily married, he loved his wife and eventually had two sons Sri Chand in 1494 and Lakshmi Chand three years later. Now that he had a family of his own Guru Nanak was persuaded by his parents to take a job as an accountant in charge of the stores of the Muslim governor of Sultanpur Daulat Khan Lodi. Guru Nanak agreed and was joined by his family and an old Muslim childhood friend Mardana, a musician by profession. Guru Nanak would work during the days, but early in the mornings and late at nights, he would meditate and sing hymns accompanied by Mardana on the rabab ( a string instrument). These sessions attracted a lot of attention and many people started joining the two.
