In recognition of its lexicographical attributes, the Mahan Kosh is noteworthy for its nuanced treatment of terminology that has become archaic or undergone semantic shifts. As a result, it remains an indispensable resource for students of Sikh studies, its relevance unmarred by the passage of time since its initial publication. Bhai Kahn Singh, the mastermind behind this feat of erudition, deserves to be counted among the great encyclopedists of the modern era.

These hallmarks of excellence in lexicography, combined with the comprehensiveness of his coverage, distinguish Bhai Kahn Singh as a preeminent theologian, deserving of recognition among the pantheon of great intellectuals."
