The theme of chapter 41 in Tanya, that Hashem is standing over us, is to arouse fear of Heaven. However, the Rebbe applied this idea in many areas of Avodas Hashem, including as a way to find calm and peace, by trusting in Hashem.
Reb Aharon Leizer Tzeitlin, the legendary Shliach to Tzfas, was under great financial pressure, with the preschool network that he ran. He wrote to the Rebbe, sharing his situation. Between the lines, his downheartedness was felt.
“Your letter was received,” the Rebbe responded in his holy handwriting. “And it is surprising that you don’t know verbatim, and in your heart, the words of the Tanya Perek Mem Alef: Behold Hashem is standing over you, etc.”
The Rebbe ended with a clear directive. “Place these words in your pocket, and in the pocket of your heart.”
