In the year 1487, Guru Nanak was married to Mata Sulakhni ji, and they had two sons, Sri Chand and Lakhmi Das. The family, accompanied by Bhai Mardana, a Muslim childhood friend of Guru Nanak, then moved to the town of Sultanpur Lodhi, where Guru ji took the job of an accountant in charge of the stores of the local Governor. Here, Guru Nanak worked during the days, but during the early mornings and late nights, he meditated and sang hymns accompanied by Bhai Mardana on the rabab (a stringed instrument). During one of those early mornings while bathing in “Vain Nadi” (a small river), Guru Nanak heard God‘s call to dedicate himself completely to the service of humanity. The very first sentence which he uttered then was, "There is no Hindu, no Musalman (Muslim)". Stating that he had been taken to the God's court and given a divine mission, Guru Nanak then began the next stage of his life, to preach his unique doctrine (Sikhi) to the entire world.
