At the time of Guru Nanak Dev Ji, there was a basic Punjabi alphabet. Guru Angad Dev Ji further developed the alphabet to give us the Gurmukhi script that we have today. The Gurmukhi alphabet helped to maintain the purity of Gurbani. The name “Gurmukhi,” means “Guru’s script.” While Sanskrit was taught to high-caste Hindus, Gurmukhi was made accessible to everyone. This allowed people from any background to understand Sikhi and Gurbani. Building on Their love for seva, Guru Angad Dev Ji started schools to help the underprivileged, teaching them Gurmukhi personally.
