“Apenny for your thoughts” goes the famous aphorism. But some thoughts are priceless. There’s one particular contemplation that has crucial and far-reaching implications. It can save one from sin provide him with a sense of self-esteem offer him insight into the way Hashem runs the world and soothe his resentment toward another Jew.

This idea is central to the meaning of a brachah recited on an exceptional occasion. When one in is in the presence of 600000 Jews — a rare circumstance — the halachah instructs him to recite a singular brachah: “Baruch Chacham harazim — blessed is the Wise Keeper of the secrets” (Berachos 58a). What is the meaning of this declaration?

With their broad vision our Sages perceived things differently than we. Amidst a crowd we typically marvel at the sheer number of human beings; they chose to celebrate not the collective mass but the individuality of each of the congregants. Accordingly they composed a brachah to praise the One Who knows the secrets the unique thoughts of each person.

Our Place in His world 

The Tenth Principle of the Rambam’s Thirteen Principles of Faith states: I believe with complete faith that Hashem knows the thoughts and deeds of all human beings as it is written “He fashions their hearts all together and He understands all their deeds.”

With this Principle we begin the third and last subgroup of the thirteen fundamentals. The first group of beliefs was about Hashem. It included His existence oneness and lack of physical form. The second group centered on the Torah its immutability and Divinity. The last group is about us. Once we know that Hashem is our Creator and that He has given us instructions for life what are our roles and responsibilities and what future can we anticipate?

This key cluster of Principles begins with the knowledge that Hashem is fully cognizant of everything we do and think.

Rav Hirsch points out that it’s the Tenth Commandment lo sachmod — do not covet — that sets the seal upon the Aseres Hadibros. This is not only because it’s the last Dibrah but because it’s the finest proof of the Divine origin of the Decalogue. No mortal king would ever prohibit an emotion for desires of the heart cannot be enforced or monitored. Only the Creator can claim to know our inner feelings.

The Chofetz Chaim famously declared that the proliferation of modern inventions in the past century is not so much a reflection of an advanced civilization as it is a gift from Hashem to reinforce our belief in His omniscience. Telephones he explained model the Ozen shomaas the Ear that hears from afar. Tape recordings verify that all words can be meticulously documented. Similar lessons can be drawn from later inventions: ultrasound technology sees hidden images videography records activities and the global positioning system (GPS) follows our every movement.

The Rambam separated this Principle of Hashem’s omniscience from the following Principle that of reward and punishment. What are the ramifications of this Principle beyond its serving as a deterrent to sin?

The Ramban (Shemos 12:16) tells of the pagan philosophy that affirmed Hashem’s existence as Creator yet claimed “azav Hashem es ha’aretz — Hashem has abandoned the earth.” In contrast we believe that Hashem directly sustains the world and that if He were to withdraw His influence even momentarily the world would revert to nothingness.

Our knowledge of Hashem’s omniscience shapes our relationship with Him. We’re not only subjects of the King but we stand before Him constantly. Life takes on great meaning when we consider that Hashem observes us constantly cares about us and responds to the choices we make. This supervision and interest is termed “Hashgachah.”

Why They Did It 

Rav Moshe Shapiro points out that there is still more to be derived from this Principle. The Ramchal explains that Hashem uses His knowledge of our thoughts and deeds not only to dispense reward and punishment but also to guide the world to its ultimate culmination.

While it’s true that free will is allotted to mankind and that our actions lead the way Hashem’s Will always prevails. This intricate interplay of man’s choices and the Divine plan elucidates a fascinating gemara (Avodah Zarah 2b) which relates a conversation between Hashem and the nations at the end of days:

In the future Hashem will hold on to the Sefer Torah and declare: Whoever occupied himself with the Torah come and take your reward. 

The Romans will approach and Hashem will inquire: What did you accomplish for Torah? 

They will reply: Ribbono shel Olam we created many marketplaces built many bathhouses and amassed much gold and silver. And we did it all for Yisrael to enable them to study Torah. 

And Hashem will answer: Fools of the world! All that you did was for your own purposes! 

Then the Persians will enter and make their claim: We designed many bridges conquered many cities and waged many wars. And we did it in order to enable Yisrael to engage in Torah. 

And Hashem will answer again: Fools of the world! All that you did was for yourselves! 

The Brisker Rav wonders why Hashem labels them as “fools.” Weren’t they blatant liars? They had no intention to benefit Klal Yisrael! Secondly what possessed them to utter such outright lies? Isn’t the end of days a time when dishonesty and falsehood yield to the truth?
