It can take a long time until something is invented. But once one person has already broken through the creative barrier, others can easily follow suit and produce the same results. For example, it took many years until someone invented the first railroad train. But after one person invented it, many others built similar railroad trains. It doesn't take a genius to model the work of a genius!
The same principle applies to spiritual growth. There were people in previous generations who reached great heights. They were innovators in the field of Jewish metaphysics. Since we now have them as models, the knowledge of how to reach spiritual greatness is available to all of us.
Today, think of five great people you have met or read about. What qualities do you most respect in each one? As you reflect on these qualities, consider how you would apply these same attributes to yourself.
