Every action we do that is in accordance with Hashem’s will has an unbelievable impact on the higher spiritual worlds. The same is true of every mitzvah we perform and every word of Torah that we study.
Although this spiritual impact is not visible in our physical world, it is certainly real. Our positive actions trigger, in turn, Hashem’s divine light and goodness that descend into our world and can bring physical results as well.
This idea explains the Talmud’s statement (Sotah 21a) that “Torah and mitzvot save and protect.” Our Torah learning and good deeds create a spiritual shield that helps protect us, including our soldiers at war, with their powerful spiritual influence.
The powerful influence of our Torah learning and good deeds create a spiritual shield that helps protect our entire nation, including our soldiers at war.
