Kavi Santokh Singh was a Sikh literati, poet, hagiographer, and historian. Santokh Singh was such a prolific writer that the Sikh Reference Library at Darbar Sahib Amritsar was named after him, located within the Mahakavi Santokh Singh Hall. In addition to "Great Poet" (Mahākavī) Santokh Singh was also referred to as the Ferdowsi of Punjabi literature, Ferdowsi wrote ~50,000 verses while Santokh Singh's Suraj Prakash totals ~52,000. Other scholars have thought of Santokh Singh as akin to Vyasa. Gottlieb Wilhelm Leitner in 1883 wrote that, "Santokh Singh of Kantal in the Karnal District, has rendered his name immortal" through the production of his works.

Gurū Nānak, also known as Bābā Nānak, was the founder of Sikhism and is the first of the ten Sikh Gurus. His birth is celebrated as Guru Nanak Gurpurab on Katak Pooranmashi, i.e. October–November.
