Sikhism is a monotheistic religion founded in the late 15th century in the Punjab region of South Asia by Guru Nanak Dev Ji and subsequently developed through the teachings of ten successive Sikh Gurus (the last one being Guru Gobind Singh). It is known for its deep spiritual and community-oriented philosophy.

Origins: Sikhism was founded by Guru Nanak, who was born in 1469 in what is today Pakistan. He emphasized meditation on the name and message of God, equality among all people, and living a honest life.

Guru Period: Sikhism was shaped by the tenets and lives of the ten Gurus from 1469 until 1708. Each Guru added to and reinforced the messages taught by Guru Nanak.

Formation of the Khalsa: In 1699, Guru Gobind Singh, the tenth Guru, formalized the collective identity of the Sikh community by inaugurating the Khalsa, a spiritual brotherhood and sisterhood devoted to purity of thought and action.

One God: Sikhism teaches the existence of one, formless God, accessible to everyone through meditation and devotion.

Equality: A fundamental principle in Sikhism is the equality of all humans, regardless of caste, creed, or gender.

Community and Service: Sikhs emphasize the importance of doing good actions rather than merely carrying out rituals. Community service, known as “Seva,” is integral to their practice.

The Three Pillars: Guru Nanak established three principles which guide Sikh life: Naam Japo (focusing on God), Kirat Karo (earning an honest, pure and dedicated living), and Vand Chakko (sharing with others).

The Five Ks: Khalsa Sikhs are expected to abide by the five Ks: Kesh (uncut hair), Kara (a steel bracelet), Kanga (a wooden comb), Kacchera (cotton underwear), and Kirpan (steel sword).

Langar: The practice of a community kitchen, or Langar, is central to Sikhism, where a free meal is served to all visitors, without distinction of religion, caste, gender, economic status or ethnicity.

Gurdwara Services: Sikhs worship in a Gurdwara, where the Sikh scripture, Guru Granth Sahib, is read, and hymns are sung. Everyone is welcome to join.

Art and Music: Sikh culture is rich in art, music, and poetry that reflects the religion's ethos and history. Gurbani Kirtan, spiritual songs based on the scriptures, play a crucial role in religious ceremonies.

Martial Tradition: Historically, Sikhs are known for their martial tradition. This was particularly developed during the time of Guru Gobind Singh who formed the Khalsa as a community of warriors.

Global Community: Today, there are significant Sikh communities worldwide, particularly in India, the United Kingdom, Canada, the United States, and Australia.

Contemporary Issues: Sikhism faces contemporary issues such as the fight for Sikh identity, with debates over the right to wear articles of faith in schools and workplaces, and issues of assimilation and preservation of cultural heritage.

Sikhism is a religion with a deep devotion to the remembrance of God coupled with active service to the community. It promotes a way of life that balances spirituality with practical living and is noted for its commitment to equality and justice.
