Explain Sikhism.

Sikhism is a monotheistic religion founded by Guru Nanak in the 15th century in the Indian subcontinent. It emerged as a distinct faith, blending elements of Hinduism and Islam, with a focus on the oneness of God, social justice, and equality. The teachings of Sikhism are enshrined in the Guru Granth Sahib, the central religious scripture and the eternal Guru for Sikhs.

Key principles of Sikhism include belief in one formless God (Waheguru), equality of all human beings irrespective of caste, creed, or gender, and the importance of honest living and selfless service. Sikhs follow the guidance of the ten Sikh Gurus, with Guru Nanak being the first and Guru Gobind Singh being the last human Guru. The tenth Guru, Guru Gobind Singh, institutionalized the Guru Granth Sahib as the eternal Guru to guide Sikhs.

Sikh identity is marked by the Five Ks, including uncut hair (kesh), a wooden comb (kangha), an iron bracelet (kara), a ceremonial sword (kirpan), and special undergarments (kachera). The central tenet of Sikhism is the concept of Naam Japna (meditating on God's name), Kirat Karni (earning an honest living), and Vand Chakna (sharing with others).

Sikhism promotes a life of devotion, humility, and service to humanity. Sikhs congregate in Gurdwaras for congregational worship, where the Guru Granth Sahib is revered. The religion emphasizes the equality of all, irrespective of social or economic status, and rejects discrimination and rituals. Sikhism has a global presence, with significant communities in India, the diaspora, and beyond.
