As a chemical element, cadmium interacts physically and chemically with other substances. Unification thought calls such interactions "give and take action" (or giving and receiving action). These types of interactions are part of the larger picture in which the world is a collective whole, built on relationships between its individual parts. Unification thought endeavors to expand our consciousness of the things of this world, moving from small, individual entities (such as atoms and molecules) to the relationships they have with one another, thereby building larger and larger entities, until we can view the world as a collective whole.
Cadmium and its compounds are toxic to humans. Yet, by investigating their properties and learning how to prepare them and use them, we have found many useful applications. These efforts are manifestations of human ingenuity, creativity, and responsible action, which are attributes of our spiritual nature. They indicate that we possess an internal drive toward understanding nature and creating new things, a drive that is endowed by God so that we can fulfill the Third Great Blessing of establishing harmony with and stewardship of true love over the created world.
The usefulness of cadmium and its compounds indicates that this element serves the larger purpose, or the "purpose of the whole." From a Unification perspective, cadmium and its compounds teach us a lesson for our own spiritual growth: namely, to live for the sake of others, especially in this world that is filled with suffering on account of spiritual as well as material poverty, hunger, and disease. By taking responsibility in this manner, we transcend the level of mere survival and travel the path toward inheriting God's nature. Eventually, we can vibrate with God's spirit and become channels for God's love to flow through us to others and to the rest of creation. In so doing, we can fulfill the Three Great Blessings and establish a world of peace and harmony.
