Despite these traumatic experiences as prisoner of war, during this period, Ven. Nyanaponika Thera completed the German translations of the Sutta Nipata, the Dhammasangani (the first book of the Abhidhamma Pitaka) and its commentary. He also compiled an anthology of texts on Satipatthana Meditation. That was when at Diyatalawa and the balance writing of what Ven. Nyanaponika Thera began was concluded at Dehra Dun, India.
