It is part of the Gurbanishabad called Mool Mantra which is repeated daily by Sikhs. This word succeeds the word "Ek-onkar" which means "There is only one constant" or commonly "There is one God". The word sat means "true/everlasting" and nam means "name".[2] In this instance, this would mean, "whose name is truth".[3] Satnam is referred to God as the Name of God is True and Everlasting.[4]
The word nam in Sikhism has two meanings. "It meant both an application and a symbol of the All-pervading Supreme Reality that sustained the universe. Guru Nanak in his teachings emphasized the need of repeating Sat-Nam to realize the All-pervading Supreme Reality."[5]
