"From morning till night everything was performed [by Helena Roerich] for the benefit of humanity. The broadest correspondence was carried on; books were written; works of many volumes translated; and all this was done in an amazingly tireless spirit. Even the most difficult circumstances were conquered by true faith which became real straight-knowledge. Surely, wonderful accumulations are necessary for such knowledge! All young people should know of this tireless life as a vital example of austere achievements, benevolence, and constructiveness. When the difficulties of this inspirational work are known, it will be particularly helpful toward the realization that incessant advancement can be made. Often, one thinks that everything is hopeless, that good is defenseless against evil, so great are the delusions resulting from human despair. Therefore, real vital examples are indeed most important; and we may rejoice at the encouragement such an example as this provides for all beginners in constructive work."
