Guru Nanak (1469–1539 CE) was born in a village called Talwandi, about 40 miles from Lahore in what today is Pakistan. He is said to have been from a merchant family. He married and had two sons. In his early twenties, Nanak moved to Sultanpur, an important town on the main road between Lahore and Delhi, where he worked as a clerk in the Lodi administration. When he was about thirty years old, he had an experience that he described as a revelation—a direct encounter with God that shaped the rest of his life.
The stories Sikhs later told about Guru Nanak, called janam sakhis, recount his childhood inwardness, along with his engagement with social issues. They tell of his honesty and devotion to truth as a youth. And they tell the story of this remarkable and transformative encounter with God. One day Nanak went to bathe in a river, accompanied by a friend. Nanak mysteriously disappeared, and his frantic friend, after several attempts to rescue him, returned to Sultanpur with the dreadful news and the clothes Nanak had left on the bank. Three days later, however, Nanak reappeared. He emerged from the water and his first words were: “There is neither Hindu nor Muslim.”
