The second volume of “Leaves of the Diary” of N.K. Roerich includes essays written in 1936–1941. Capturing modernity, the published Diary Sheets are remarkable for their sincerity and power of persuasion. The essays in this volume are a synthesis of spiritualizing and transformative ideas in the light of the evolutionary provisions of the Living Ethics, the crystallization of the ethical and philosophical views of the humanist thinker. The texts of the Diary Sheets are reproduced from the materials of the ICR archive. A significant part of the essays is published for the first time.
