Sikhism, is a monotheistic religion founded during the 15th century in the Punjab region, by Guru Nanak Dev which continued to progress with ten successive Sikh gurus (the last teaching being the holy scripture Gurū Granth Sāhib Ji). It is the fifth-largest organized religion in the world, with approximately 30 million Sikhs. This system of religious philosophy and expression has been traditionally known as the Gurmat (literally 'wisdom of the Gurū'). Punjab, India is the only region in the world with a majority Sikh population.
Sikhs are expected to embody the qualities of a "Sant-Sipāhī"—a saint-soldier. One must have control over one's internal vices and be able to be constantly immersed in virtues clarified in the Guru Granth Sahib.
The principal beliefs of Sikhi are faith in Waheguru—represented by the phrase ik ōaṅkār, meaning one God, along with a praxis in which the Sikh is enjoined to engage in social reform through the pursuit of justice for all human beings. Sikhi advocates the pursuit of salvation in a social context through the congregational practice of meditation on the name and message of God. The followers of Sikhi are ordained to follow the teachings of the ten Sikh gurus, or enlightened leaders, as well as the holy scripture entitled the Gurū Granth Sāhib Ji, which, along with the writings of six of the ten Sikh Gurus, includes selected works of many devotees from diverse socio-economic and religious backgrounds. Guru Gobind Singh Ji, the tenth guru, conferred the leadership of the Sikh community to the Gurū Granth Sāhib and the corporate body of the Khālsā Panth (the Granth and the Panth). Sikhi's traditions and teachings are associated with the history, society and culture of Punjab.
