He subsequently won renown in both fields Sikh learning and Hindi poetry. Among his poetical works, Gumpad Prem Prakas, a historyr.of the Gurus in over 16,000 stanzas, is especially notable.
Only its tenth mandal or section dealing with the life of Guru Gobind Singh was published at Lahore in 1882 under the title Gurbilas Dasvin Patshahi Guru Gobind Singh Charitra.A couplet in the exordium shows that the work was taken up at Najibabad in 1923 Bk/AD 1866 (when the poet was still in his teens), and the mention further of nine other works by the author and of his visit to Amritsar and Lahore in 1937 Bk/AD 1880 shows that the composition of Gurupad Prem PrakaswsiS spread over 14 years. A much shorter account of the ten Gurus, the 88page Gur Kavitavali, was published at Amritsar in 1886. Another published work of Bava Sumer Singh is Khalsa Pahchasika (Hindi), Light Press, Banaras, 1877.
