What is most difficult and dangerous for us moderns in the study of history is to overcome the tendency to see our malice reflected in the actions of those who lived in a time not yet corrupted by marketing. We are inclined to find, always, deceit and self-interest behind every act and every word, when, in truth, not to go into the moral question, these did not reward with the generosity and security that they do now. To the modern mind purity of intention and acting without expecting anything in return are strange; therefore, in order to understand well some past lives, it is necessary, first of all, to undergo an evolution.
