Sikhism begins with guru-nanak‘s declaration after an encounter with the divine: “There is no Hindu, there is no Muslim.” Its tradition holds that there is one God, without rival or form; that all people are equal before that God; and that liberation comes through naam-simran — remembrance of the divine Name.
Ten human Gurus followed Nanak, ending with Guru Gobind Singh, who declared that the line of living Gurus would end — and that scripture (guru-granth-sahib) and community (panth) would together be the Guru thereafter.
Sikhism weaves contemplative interiority with active service (Seva). The langar — the free community kitchen that welcomes anyone — is its most visible expression.
