Understanding these two attributes of netzach and hod gives us a new perspective into understanding what is happening in the world. We cannot look at the acts of God merely at face value. For instance, the suffering of the righteous may be a test in order to heighten their reward, or a way to cleanse them in this world of their few sins so that they are pure and perfect in the World to Come. The wicked may be prospering in order that their feeling of complacency forestalls their repentance or in order that they should receive their entire reward on earth so their later destruction can be total. These sefirot mark a turning point.
Feet are usually only the means for a person's activity.
The hands are the main instrument of action and the feet are simply a vehicle to bring the person to the place in which he wishes to execute that action. Secondly, the distinction between right and left foot is nowhere as pronounced as the distinction between the left and right hands. Similarly, while the distinction between chesed and gevurah is sharp, the distinction between netzach and hod is less sharp. Both are a mixture of chesed and gevurah and therefore the distinction is blurred. This is the reason why we have a harder time discovering the motive for God's actions.
