His biography of 'Abdu"l-Bahā is still read today, as well as Phelps" Notes, his transcription of Mādhav Prasād Sinha"s talks that is standard fare in the literature of the Radhasoami Satsang of Soami Bagh, Āgrā.

Except for a brief incident wherein Sanghamitta got extremely irritated and vocal with a translator, the visit was cordial and fruitful and resulted in Phelps"s biography of 'Abdu"l-Bahā (dedicated to Master of Arts de South Canavarro).
