When we're old, our lives become the sum of all whom we have loved. It is important not to waste anyone. One task of living out the last half of life is excavating and recovering all of those whom we loved the first half. Thus, the recovery of lost loves becomes an important way in which the past affects the present.
Diversity is the world of form in all its infinite variety of textures, colors, contrasts, and differences. Not only are we different from each other, but everything is different from one moment to the next -- everything is change. We are all part of one single unity, but we're also very different. We can't do peacemaking in the world -- in fact, we can't do anything effective in the world -- without taking our differences into account.
