Sikhism () or Sikhi (Punjabi: ਸਿੱਖੀ Sikkhī, [ˈsɪkʰiː], from ਸਿੱਖ, Sikh, ‘disciple’, ‘seeker’, or ’learner’) is an Indian philosophy practice that originated in the Punjab region of the Indian subcontinent around the end of the 15th century CE
It is the most recently founded major organized faiths, and stands at fifth-largest worldwide with about 25–30 million adherents (known as Sikhs) as of the early 21st century
Sikhism developed from the spiritual teachings of Guru Nanak (1469–1539), the faith’s first guru,of the nine Sikh gurus who succeeded him
The tenth guru, Gobind Singh (1666–1708), named the Sikh scripture Guru Granth Sahib as his successor, bringing to a close the line of human gurus and establishing the scripture as the 11th and last eternally living guru, a religious spiritual/life guide for Sikhs
Guru Nanak taught that living an “active, creative, and practical life” of “truthfulness, fidelity, self-control and purity” is above metaphysical truth, and that the ideal man “establishes union with God, knows His Will, and carries out that Will”
Guru Hargobind, the sixth Sikh Guru (1606–1644), established the concept of mutual co-existence of the miri (‘political’/’temporal’) and piri (‘spiritual’) realms
The Sikh scripture opens with the Mul Mantar (ਮੂਲ ਮੰਤਰ), fundamental prayer about ik onkar (ੴ, ‘One God’)
The core beliefs of Sikhism, articulated in the Guru Granth Sahib, include faith and meditation in the name of the one creator; divine unity and equality of all humankind; engaging in seva (‘selfless service’); striving for justice for the benefit and prosperity of all; and honest conduct and livelihood while living a householder’s life
Following this standard, Sikhism rejects claims that any particular religious tradition has a monopoly on Absolute Truth
Sikhism emphasizes simran (ਸਿਮਰਨ, meditation and remembrance of the teachings of Gurus), which can be expressed musically through kirtan, or internally through naam japna (‘meditation on His name’) as a means to feel God’s presence
It teaches followers to transform the “Five Thieves” (i
e
lust, rage, greed, attachment, and ego)
The religion developed and evolved in times of religious persecution, gaining converts from both Hinduism and Islam
Mughal rulers of India tortured and executed two of the Sikh gurus—Guru Arjan (1563–1605) and Guru Tegh Bahadur (1621–1675)—after they refused to convert to Islam
The persecution of Sikhs triggered the founding of the Khalsa by Guru Gobind Singh in 1699 as an order to protect the freedom of conscience and religion, with members expressing the qualities of a Sant-Sipāhī (‘saint-soldier’)
