T. W. Rhys Davids encouraged, his then pupil, Caroline to pursue Buddhist studies and do research about Buddhist psychology and the place of women in Buddhism. Thus, among her first works were a translation of the Dhamma Sangani, a text from the Theravāda Abhidhamma Piṭaka, which she published under the title "A Buddhist manual of psychological ethics: Being a translation, now made for the first time, from the original Pāli, of the first book in the Abhidhamma Piṭaka, entitled: Dhamma-sangaṇi (Compendium of States or Phenomena)" (1900); a second early translation was that of the Therīgāthā, a canonical work of verses traditionally ascribed to early Buddhist nuns (under the title "Psalms of the Sisters" ).
