Likutei Moharan 67:5/ליקוטי מוהר"ן ס״ז:ה׳

15. One must then see to elevate glory/ Malkhut from their midst. This is accomplished through tzedakah (righteousness/charity), as in “Charity saves from death” (Proverbs 10:2). Giving tzedakah elevates and rescues [glory/ Malkhut] from the aspect of “Her feet descend to death,” thus turning TZeDeK into TZeDaKah .

2Tzedakah corresponds to the five ChaSaDim (benevolences). This is because tzedakah is the aspect of CheSeD (lovingkindness), as our Sages, of blessed memory, taught (Sukkah 49b): Charity has value only in proportion to the lovingkindness it contains, as it is written (Hosea 10:12), “Sow for yourselves seeds of charity, and you will reap in accord with kindness.”

3By means of the five benevolences we add a Heh, so that tzedek becomes tzedakaH. This is paralleled in the Torah, which mentions tzedakah five times, corresponding to the five benevolences, which are the aspect of tzedakah .

4This is the meaning of “Who raised up one from the east that called forth strict justice wherever he set his foot” (Isaiah 41:2). “Who raised up one from the east” is the aspect of tzedakah, as in “I will bring your seed from the east” (ibid. 43:5) ; the aspect of “Sow for yourselves seeds of charity….” As a result, “that called forth strict justice wherever he set his foot”—i.e., on account of tzedakah, tzedek calls forth the feet and raises them up from the aspect of “Her feet descend….”

5This is also the meaning of “Your strict justice will go before you” (Isaiah 58:8). In other words, tzedek will be able to go—i.e., the aspect of raising the feet, which are the means for going. This is “will go liphaneikha (before you)”—specifically “liPhaNeIkha,” since this elevates glory/ Malkhut to the radiance of the PaNIm, as explained above.
