Chapter I
What it means
Ik Onkar is the Sikh creed in two characters. Ik is the numeral one, written as a figure rather than a word so that it cannot be misread. Onkar names God as the creative power present in everything. Together: there is one God, the source of all that exists.
For Sikhs this oneness means that all people are equal before God, whatever their religion, caste or sex, and that God can be found within every person.
Chapter II
Where it comes from
Ik Onkar opens the Mul Mantar, composed by Guru Nanak (1469–1539), the founder of Sikhism, and placed at the beginning of the scripture first compiled by Guru Arjan in 1604 as the Adi Granth and now revered as the Guru Granth Sahib. Each section of the scripture begins with it.
Chapter III
Where you see it today
Ik Onkar is written over gurdwara doors, on the canopies over the scripture, on jewellery, on vehicles and in homes. It is spoken and sung daily in Sikh prayer.
