The "Ten Gurus" refers to the ten spiritual leaders of the Sikh faith, who played a crucial role in shaping its beliefs and practices. The first Guru, Guru Nanak, founded Sikhism in the 15th century, emphasizing the oneness of God and equality among all people. Each subsequent Guru contributed teachings and writings that are compiled in the Guru Granth Sahib, the holy scripture of Sikhism. The last of the Ten Gurus, Guru Gobind Singh, established the Khalsa, a collective of initiated Sikhs, in 1699. This community promotes values such as courage, selflessness, and devotion to God. The teachings of the Gurus continue to guide millions of Sikhs around the world today.
