“Gurmukhi” is a sacred script based on the transformative power of the sound current. lt derives from a Brahmi script in use between 5 B.C. and 350 A.O., before it branched off into a variety of other scripts.
The Gurmukhi script was developed by Guru Angad Dev Ji, the second Sikh Guru. Guru Angad put it into the form used in most of the Siri Guru Granth Sahib and other Sikh writings.
The literation translation of “Gurmukhi” is “coming from the mouth of the Guru.”
