Guru Nanak Dev
When Guru Nanak was a child he refused the upanayana (holy thread) to initiate him into the Hindu religion. Later in his life he married Mata Sulakhani with whom he had two sons. They were called Sri Chand and Lakshmi Das. According to the Sikh religion, one day he was bathing in the river and god took him up to heaven. His family members were very worried as they had thought he died. After three days he returned with the message of god. He gave up his job to spread the message on how to be a good person.
