Gurmukhi script

Guru Angad is credited in the Sikh tradition with the Gurmukhi script, which is now the standard writing script for Punjabi language in India, in contrast to Punjabi language in Pakistan where now a Perso-Arabic script called Shahmukhi is the standard. The original Sikh scriptures and most of the historic Sikh literature have been written in the Gurmukhi script.

Guru Angad standardized and made improvements to the scripts of the region to create the Gurmukhi script. Examples of possible forerunners of the script including at least one hymn written in acrostic form by Guru Nanak, and its earlier history is yet to be fully determined.

He also wrote 62 or 63 Saloks (compositions), which together constitute about one percent of the Guru Granth Sahib, the primary scripture of Sikhism. Rather than contribute hymns, Angad's importance was as a consolidator of Guru Nanak's hymns. Guru Angad would also supervise the writing down of Nanak's hymns by Bhai Paira Mokha and scrutinize the resulting compilation, preparing the way for a Sikh scripture, as well as the beginning of a vernacular Punjabi literature, as tradition holds that he may have also commissioned an account of Guru Nanak's life from earlier disciples. The collection of hymns would also be increasingly important for the expanding community.

Langar and community work
Guru Angad is notable for systematizing the institution of langar in all Sikh temple premises, where visitors from near and far could get a free simple meal in a communal seating. He also set the rules and training method for volunteers (sevadars) who operated the kitchen, placing emphasis on treating it as a place of rest and refuge, being always polite and hospitable to all visitors.

Guru Angad visited other places and centres established by Guru Nanak for the preaching of Sikhism. He established new centres and thus strengthened its base.

Mall Akhara
The Guru, being a great patron of wrestling, started a Mall Akhara (wrestling arena) system where physical exercises, martial arts, and wrestling was taught as well as health topics such as staying away from tobacco and other toxic substances. He placed emphasis on keeping the body healthy and excersising daily. He founded many such Mall Akharas in many villages including a few in Khandur. Typically the wrestling was done after daily prayers and also included games and light wrestling.
