GURMUKHI is the name of the script used in writing primarily Punjabi and, secondarily, Sindhi language. The word gurmukhi seems to have gained currency from the use of these letters to record the sayings coming from the mukh (lit. mouth or lips) of the (Sikh) Gurus. The letters no doubt existed before the time of Guru Angad (even of Guru Nanak) as they had their origin in the Brahmi, but the origin of the script is attributed to Guru Angad. He not only modified and rearranged certain letters but also shaped them into a script. He gave new shape and new order to the alphabet and made it precise and accurate.
PARAS BHAG is an adaptation into Sadh Bhakha, in Gurmukhi script, of Abu Hamid Muhammad al Ghazzali`s Kimid iSa`ddat, an abridged edition in Urdu of his Ihyd ul Ulum, in Arabic. The work was first published in 1876. Several of the manuscript copies prior to that date are still in circulation. An edition in Devanagari script was brought out in 1929. The question as to who adapted the work into Bhakha and when has not been fully resolved. According to one tradition, the version in Gurmukhi characters was prepared towards the close of the seventeenth century at Anandpur by Sayyid Badr ud Din of Sadhaura at the instance of Guru Gobind Singh (1666-1708).
