Psalmów 55:23 Kabała: Ohr Ne'erav, Sha'arei Kedusha & Sha'arei Orah

[However,] lest one think that since [the worshipper] does not pursue his [mundane] needs he does not receive a reward and benefit from this world, God forbid, the verse considers him “as though he had prayed all the day.” This is [the meaning of the verse] Cast your burden upon the Lord and He will sustain you (Ps. 55:23). Thus the man’s intent is the unification [of Tiferet and Malkhut] and the needs of his [eternal] world. He seeks nothing save that [God] should sustain him. Thus [his utterance] was called “prayer.” Though he was occupied with the mystery of the unification and [related] matters, [nonetheless] he is aided with regard to the affairs of the world “as though he had prayed all the day.” Now when [the passage] states: “What is shigeonot?”, [implying] that it should have been called [something] different, we now understand that [“prayer”] ranks above “psalm” and is more honorable than shigeonot and praises (shebaḥim). Thus he explained [that shigeonot is] a word connoting error …

In contrast, there is no greater quality than trust in HaShem-יהו״ה, blessed is He, as written,⁴⁶⁵Psalms 2:12 “Happy are all who trust in Him.” A person who has this quality is faithful that there is a God in the world, who is all-capable and supervises over everything. It thus is written,⁴⁶⁶Jeremiah 17:7 “Blessed is the man who trusts in HaShem-יהו״ה, HaShem-יהו״ה will be his security.” Such a person is certain that he will not lack sustenance, as written,⁴⁶⁷Psalms 55:23 “Cast your burden upon HaShem-יהו״ה and He will sustain you.” However, this applies on condition that his trust in HaShem-יהו״ה is truly sincere, with all his heart and without doubt. This is evident by the fact that if he truly trusts in HaShem-יהו״ה, blessed is He, he will occupy himself in studying His Torah and fulfilling His mitzvot with all his heart and without any misgivings.

Also, never accept gifts, for whosoever despises receiving gifts will live,²⁷⁵Proverbs 15:27 for it is HaShem-יהו"ה who impoverishes or gives wealth.²⁷⁶Samuel I 2:7 It is He who gives you the strength to accomplish.²⁷⁷Deuteronomy 8:18 Therefore, cast your needs upon HaShem-יהו"ה with all your heart and He will sustain you.²⁷⁸Psalms 55:23 May the fear of HaShem-יהו"ה, blessed is He, be upon your face, so as not to commit any of the 365 Torah prohibitions.²⁷⁹Sefer Yere’im 352 Take particular care not to fall into bad character traits, which are like sourdough²⁸⁰Talmud Bavli, Brachot 17a that causes physicality to rise, especially those bad character traits that are readily found and therefore trampled upon.²⁸¹Talmud Bavli, Avodah Zarah 18a; Rashi to Deuteronomy 7:12
