The distinction between Adi Granth and Guru Granth Sahib is best understood as a difference in stage and status rather than in essence. The term *Adi Granth*, literally “First Book,” refers to the original compilation prepared under Guru Arjan, the fifth Sikh Guru, and completed in 1604. This foundational volume gathered the hymns of the first five Sikh Gurus along with the compositions of various saints and bards. At this stage, the Sikh line of human Gurus continued, and the text, though central and revered, was not yet vested with the role of final spiritual authority.

The designation *Guru Granth Sahib* marks a later and more elevated phase in the life of this same scripture. Over time, the original Adi Granth was expanded to include the hymns of Guru Tegh Bahadur, the ninth Guru, while preserving the earlier compositions intact. Guru Gobind Singh, the tenth Guru, then brought the historical line of human Gurus to a close and bestowed the status of Guru upon this scripture. From that moment, the text was not only a sacred compilation (*Granth*) but also acknowledged as the eternal, living Guru of the Sikh community, honored with the title *Guru Granth Sahib*.

Seen in this light, Adi Granth and Guru Granth Sahib are not two rival texts but two names that reflect a deepening realization of the same spiritual source. Adi Granth evokes the origin and careful compilation of the Sikh canon; Guru Granth Sahib evokes its recognized role as the final, sovereign guide for Sikh life and devotion. The journey from “First Book” to “Guru” suggests a movement from scripture as revered teaching to scripture as the abiding, personal presence of guidance.
