The Klausenberger Rebbe, zt”l, was quoted as follows: “My holy ancestor, the Rebbe of Dinov, used to say that anything that does not have a source in the Torah is not included in truth. Therefore, if I were to hear a person making the simple calculation that one plus one equals two, I would doubt his words…” until he could prove it from the Torah.
In our world, we are not used to seeing reality through the lens of Torah, but perhaps that’s why this world is in the condition it’s in.
It’s possible to fight the yetzer hara. It’s possible to look at Torah as we go through life instead of looking at physical things that intimidate us. Maybe that’s why the Shema instructs us to keep Torah constantly “upon your heart … while you sit in your home, while you walk on the way, when you lie down and when you arise…” In other words, always.
If it were not possible to succeed, we would not beg Hashem every morning, “Let not the Evil Inclination dominate us…. Attach us to the Good Inclination and to good deeds and compel our Evil Inclination to be subservient to You.”
This is the Month of Teshuvah. We really can change ourselves. We really can change the world. We can really see Mashiach ben Dovid and the Final Redemption soon in our days.
