Guru Nanak Dev Ji
The first of the Gurus and the founder of the Sikh religion was Guru Nanak. He was born at Talwandi (now known as Nankana Sahib in Pakistan) on October 20, 1469.
Guru ji mastered Punjabi, Sanskrit and Persian at an early age and in childhood revolted against ritualism, caste, prejudices, hypocrisy and idolatry.
He regarded Hindus and Muslims as equals and referred to himself as neither Hindu nor Muslim but as a brother to all those who believed in God and truth.
He made four great journeys, travelling to all parts of India, and into Arabia and Persia; visiting Mecca and Baghdad. He spoke before Hindus, Jains, Buddhists, Parsees, and Muslims. He spoke in the temples and mosques, and at various pilgrimage sites. Wherever he went, Guru Nanak spoke out against empty religious rituals, pilgrimages, the caste system, the sacrifice of widows, of depending on books to learn the true religion, and of all the other tenets that were to define his teachings. Never did he ask his listeners to follow him. He asked the Muslims to be true Muslims and the Hindus to be true Hindus.
