One lesson we can learn from the popular term, "The Atomic Age," is that we have seen in our time how the energy concealed within the minutest subatomic particles can destroy an entire city and millions of inhabitants. This is possible because within every tiny bit of matter, G-d has infused a tremendous amount of power.

If this is the case with negative activities such as warfare, so much more so is it true with regard to a Jew's spiritual potential: through the proper use of the power locked within his divine soul, one person can have an immeasurable effect on himself and on the entire world.

Furthermore, we have learned that where we once believed the world to be made up of a multitude of different elements, through examining substances at the sub-atomic level we find that they are all built of the same matter. This demonstrates the tremendous unity of creation.
