GUR SEVAK SABHA, a society formed at Amritsar on 29 December 1933 by some Sikh intellectuals and educationists to restate Sikh moral and religious values and have these reinstated in the public life of the Panth,` then severely riven by rivalries and personal ambitions of the leaders. Bava Harkishan Singh, Principal of the Guru Nanak Khalsa College at Gujranwala, Tcja Singh and Niranjan Singh, both professors at the Khalsa College at Amritsar and Narain Singh, a professor at the Khalsa College at Gujranwala, were amongst the sponsors.
GURUSHABAD RATANAKAR MAHAN KOSH, more popularly known by its shorter title Mahan Kosh, the great dictionary, by the celebrated man of letters and lexicographer, Bhai Kahn Singh, of Nabha, is a work unexcelled for its neatness and refinement of expression and monumental in its scope and size. It would indeed do justice to the title "Encyclopaedia." It is amazing how an individual conceived and planned a work of such a vast dimension and how he accomplished it single handed in a single lifetime.
