Sikhism and Shared Dharmic Themes

Sikhism originated in the Punjab region of the Indian subcontinent with Guru Nanak (1469–1539), traditionally held to have been born in Talwandi, in present-day Pakistan, into a Hindu family, in a religious environment already marked by considerable interaction between Hindu Bhakti devotionalism and Sufi Islamic mysticism. According to Sikh tradition, Guru Nanak underwent a transformative spiritual experience while bathing in a local river, after which he began an extended period of travel, known as the udasis, across the Indian subcontinent and, according to tradition, as far as the Middle East, teaching a message centered on the oneness of God, expressed in the opening phrase of Sikh scripture, ik onkar, "there is one God," and on the fundamental equality of all human beings regardless of caste, gender, or religious background. Guru Nanak rejected the necessity of ascetic renunciation, ritual sacrifice, and image worship, instead emphasizing simran, meditative remembrance of God's name, and seva, selfless service to others, principles institutionalized in the establishment of the langar, a communal kitchen offering a free vegetarian meal to all visitors regardless of background, which remains a defining feature of Sikh gurdwaras (houses of worship) worldwide.
