Nirmala also known as Nirmala Saṁpardā or Nirmal Paṅth, is a Sikh sect of ascetics. According to the traditional beliefs, the Sanatan Nirmala Sikh tradition was founded by Guru Gobind Singh in late 17th century when he sent five Sikhs to Varanasi to learn Sanskrit and Vedanta texts.

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.
