In the train of our thoughts are all the people who have helped form our lives—as ancestors, family, friends, teachers, and acquaintances. All of them watch over us from within our memories, conscious or unconscious. They guide us through the haphazard course we follow, as we do, unconsciously, with the lives of others.
At times it is given to us to look back on our course. From the crest of the present moment, if we observe carefully, we can see how the tracks of our lives have acted to shape and influence each other, and been shaped and influenced in turn.
