Our great-grandfather of blessed memory related about the Baal Shem Tov, may his merit protect us, that his tzitzis had actual life and vitality — such that they were able to sway on their own without any movement of his body. For through the holiness with which he performed the mitzvah, he drew down for them a soul and living spirit.   (Divrei Shalom, Parshas Tavo) sefaria.org.il "Send for yourself men." When we perform a mitzvah, we create angels, and therefore the mitzvah must be performed with pure thought while subduing our base traits before H'shem. (It seems the Rebbe is referring to the word "men" in the verse. "Sending men" alludes to sending angels, which are created from the mitzvos;  both are messengers sent out to fulfill a purpose.) Therefore, "send for yourself" — send up those mitzvos back to your root source,* "To survey the land of Canaan", by "surveying" your own material physicality, called artziyus, to...

 Being ignorant of the Creator and His good attributes is detrimental to trust in GD.  For whoever fails to appreciate the Creator's compassion for His creatures, His protection of them, His providence, dominion, and control over them will not be confident in Him and will not rely on Him.  Another thing that is detrimental is ignorance of the Creator's command i.e.,  His Torah, in which he charged us to rely on Him and to trust in Him pg 465

 He who takes a pledge from his fellow does so only if he is able to supply the latter with the goods for which he takes the pledge as security.  But one who demands a pledge from the Creator, may He be exalted, in the form of advancing favors, is unable to render the service that is due for them. He is not even certain that he will be able to pay his old debt, much less the new one. For the righteous man can meet his obligation to H'shem for His goodness to him only by means of the help that H'shem extends to him.  pg 463

  If there be a prophet among you, I . . . speak to him in a dream. My servant Moses is not so (12:6–7) In sleep, when the soul frees itself to a certain degree from the confines of the body, it can begin to perceive the divine essence that hides behind the material world. Moses, however, was able to see G‑dliness even when awake—for him, the material world did not conceal. (Rabbi Israel Baal Shem Tov) chabad.org The author of Chesed L'Avraham , Rav Azulai, asked Rebbe Elimelech after they had already entered the higher worlds: "How is it that I authored ten sefarim and merited that they are even studied in the heavens — but the mere mention of the name of the Rebbe, Reb Elimelech, there is a great tumult in the heavens? What did you do to merit this?" Rebbe Elimelech answered: "Every Erev Shabbos my household was full of such awe that even the maids would fall down crying, begging each other for forgiveness, saying: 'Forgive me if I offended you all week long....

 One who takes a pledge from his fellow — if he had been certain that his fellow would pay him back earlier than agreed upon and would out of sheer kindness reward him for waiting for his money with twice the sum that was owed him— then he would never have taken a pledge from him. And as for the Creator, may He be exalted, Whose benevolent and great favors, present and past, are known to us, Who is known to requite acts of charity and obedience with reward that cannot be imagined, let alone described — it is much more a disgrace to demand a pledge from Him.

When a father punishes his child, the suffering he inflicts on himself is greater than anything experienced by the child. So it is with H'shem: His pain is greater than our pain. (Rabbi Israel Baal Shem Tov) Chabad.org "When someone will ask what he will eat in  the year of Shemittah, H'shem answers  that He will send His blessings. We may ask  why the pasuk seems to say that one must  ask this question to receive this bounty. It  sounds like if one doesn’t ask, he won’t  receive the blessing?   The Noam Elimelech (Parshas Behar)  famously says in the name of his brother,  Rav Zushe zt”l, that the pasuk is actually  saying that this assurance of a new  blessing from H'shem is only necessary  When one is concerned about what will be  and asks what he will eat.  This is because the doubts this person has stopped the  original blessings that were in place, and a new blessing  is needed. If one has ...
