Karma yoga is the science of action with non-identifying. It must not be changed into "the science of action without identifying." The essence of the idea of Karma Yoga is to meet with unpleasant things equally with pleasant things. That is, in practicing Karma Yoga, one does not seek always to avoid unpleasant things as people ordinarily do. Life is to be met with non-identifying. When this is possible life becomes one's teacher; in no other sense can life become a teacher, for life taken as itself is meaningless, but taken as an exercise it becomes a teacher. It is not life that is a teacher, but ones relation through non-identifying makes it become a teacher.............................
