Soon, Singh was drawn into the Sikh fold through Bhai Gurmukh Singh, then an active figure in the
Singh Sabha Movement. In 1886, he became a principal contributor to and subsequently the second editor of the weekly
Khalsa Akhbar Lahore, a newspaper founded by Bhai Gurmukh Singh following the establishment of the
Lahore Khalsa Diwan. Singh had passed the
Gyani examination the same year and was appointed a teacher at the
Oriental College. He used the
Khalsa Akhbar as a vehicle for the spread of Singh Sabha ideas. When the Amritsar Khalsa Diwan excommunicated Bhai Gurmukh Singh, Ditt Singh responded by publishing excerpts from his book
Svapan Natak, a thinly veiled satire ridiculing the Amritsar leaders, in the
Khalsa Akhbar. This resulted in a lawsuit filed by one of the targets of the satire, which, although eventually dismissed, cost the
Khalsa Akhbar dearly in time and money to defend. The paper shut down in 1889. With support from the
Maharaja of
Nahba, the paper resumed publication in 1893, again under Ditt Singh as editor. This led to the eventual launch of an English-language weekly, titled simply
Khalsa. Through all of his Sikh Sabha activities, Singh had maintained his ties to the Arya Samaj, but in 1888, the increasing discord between the Arya Samaj and Sikh leaders led to Singh's ultimate departure from the movement. After this, he threw himself entirely into the work of the Singh Sabha. As an educator, Singh helped in the setting up of
Khalsa College, Amritsar, and wrote textbooks for the students of the college. ==Discussion with Swami Dayanand==
