Ten Gurus of Sikhs
Guru Nanak Dev (1469' 1538), founder of Sikhism, was born to Kalu Mehta and Mata Tripta, wherein the Bedi Khatri clan of a Hindu family in the village of Talwandi, now called Nankana Sahib, near Lahore. His father, a Hindu named Mehta Kalu, was a Patwari, an accountant of land revenue in the government. Nanak's mother was Mata Tripta, and he had one older sister, Bibi Nanki.
From an early age Guru Nanak seemed to have acquired a questioning and enquiring mind and refused as a child to wear the ritualistic “sacred” thread called a Janeu and instead said that he would wear the true name of God in his heart as protection, as the thread which could be broken, be soiled, burnt or lost could not offer any security at all. From early childhood, Bibi Nanki saw in her brother the Light of God but she did not reveal this secret to anyone. She is known as the first disciple of Guru Nanak.
Even as a boy, Nanak was fascinated by religion, and his desire to explore the mysteries of life eventually led him to leave home. It was during this period that Nanak was said to have met Kabir (1440-1518), a saint revered by many. Nanak married Sulakhni, daughter of Moolchand Chona, a trader from Batala, and they had two sons, Sri Chand and Lakshmi Das.
His brother-in-law, Jai Ram, the husband of his sister Nanki, obtained a job for him in Sultanpur as the manager of the government granary. One morning, when he was twenty-eight, Guru Nanak Dev went as usual down to the river to bathe and meditate. It was said that he was gone for three days. When he reappeared, it is said he was "filled with the spirit of God". His first words after his re-emergence were: "there is no Hindu, there is no Muslim". With this secular principle he began his missionary work.
He made four distinct major journeys, in the four different directions, which are called Udasis, spanning many thousands of kilometres, preaching the message of God.
Guru Nanak spent the final years of his life
