Nanak was the founder of Sikhism and the first of its ten Gurus. Born into a Hindu merchant caste, he worked as a storekeeper until a spiritual experience incited him to leave his job and family and begin a 20-year phase of travel. He eventually settled in Kartarpur, a village in Punjab, and attracted many disciples. He stipulated that meditation must be inward and rejected all external aids such as idols, temples, and scriptures. Where was Nanak said to have made his four major journeys? Discuss
