Anurag Sagar Sant Mat
"'Hazur [Baba Sawan Singh] one day told Seth Vasdev, whose car is always at Hazur’s disposal, that he should read Kabir Sahib’s Anurag Sagar (The Ocean of Intense Love). Hazur said that without studying it, one cannot fully understand the difference between Kal (the negative power) and Dayal Mat (the Path of the true and Merciful God), nor can one fully grasp the teachings of Sant Mat.’” (Rai Sahib Munshi Ram, “With the Three Masters”, Vol. 2, p.187, cited in the Introduction to, The Anurag Sagar, 1982, Sant Bani Ashram, Sanbornton, NH https://archive.org/stream/AnuragSagarOfKabir/Anurag-Sagar-Complete#page/n5/mode/1up )
Sawan's characterization of the Anurag Sagar, a Dharamdasi scripture, as essential reading in order to "fully grasp the teachings of Sant Mat" points towards a closer connection with the Dharam Das branch of Sant Mat than to the Sikh line. Of course finding all five of the five names (Panch Naam) present in Dharmdasi sources provides more evidence suggesting a connection, as they are the only known group to have been using the five names prior to the time of Tulsi Sahib. Professor Mark Juergensmeyer in, Radhasoami Reality, wrote about how, out of all the other spiritual groups in India, the one that seems closest to Sant Mat and Radhasoami is the Dharam Das group.
