Quotation к Ирмеяу 23:41

"I have set Hashem before me always."¹Psalms 16:8. This is a fundamental rule of the Torah and of the attributes of the righteous who walk before God. For we cannot compare a person's lifestyle, his activities and affairs when he is alone, to his lifestyle, and activities and affairs when he is before a great king. Similarly, his conversation and speech when he is amongst family or relatives, [cannot be compared] to what they would be in the presence of a king, because then he would certainly take special care that all his activities and conversations be refined and correct. How much more so when you contemplate that Hashem, the greatest of kings, the Holy One, blessed is He, Whose glory fills the entire world, stands above you and views your actions, as it is said: "If a person will hide in hidden places will I not see him? Says the word of Hashem, Do I not fill the heavens and the earth!"²Jeremiah 23:24. [Bearing this in mind] it is certain that you will immediately acquire a feeling of reverence and submissiveness for the awesomeness of Hashem, Blessed be He, and be ashamed [to sin] before Him.
