The Sikh scripture opens with the "Mul Mantar" (), fundamental prayer about "ik onkar" (). The core beliefs of Sikhism, articulated in the "Guru Granth Sahib", include faith and meditation on 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.
