Ek-Onkar (Sykh Symbol)

It is a symbol of the unity of God in Sikhism, and is found on all religious scriptures and places such as Gurdwaras.
The words Ek-Onkar have a firm place in Sikhism and it symbolizes a lot. The Guru Granth Sahib Ji opens with these words. Ek-Onkar means 'There is one God.'
Many Gurdwaras and Sikh organizations use this symbol on letters and other documents. In fact, many Sikhs also use this symbol on their letters.
This constant repetition of Ek-Onkar is done so that Sikhs are constantly reminded that there is only one God in the universe.
