Guru Nanak, the founder of Sikhism, was a spiritual leader and social reformer who lived in the 15th and 16th centuries in the Indian subcontinent. His message to the people was one of love, equality, and service to humanity.

Guru Nanak believed in the concept of "Ik Onkar," which means "One God." He preached that there is only one divine force that exists in all beings and that all religions lead to the same ultimate truth. He rejected the division and discrimination based on caste, creed, and gender, and emphasized the importance of unity and equality among all people.

One of the core teachings of Guru Nanak was the concept of "Naam Japna," which means remembering and meditating on the name of God. He believed that this practice could help individuals connect with the divine and lead a righteous life. He also promoted the idea of "Kirat Karo," which means earning an honest living through hard work and service to others.

He established the concept of "Langar," a community kitchen where people of all castes and backgrounds could come together to share a meal. This practice continues to this day in Sikh temples, promoting the values of equality and service.

Guru Nanak also spoke out against the prevalent social issues of his time, such as the caste system, superstitions, and ritualistic practices. He challenged the existing beliefs and customs and encouraged people to focus on inner spirituality rather than external rituals.
