Likutei Moharan 94:2/ליקוטי מוהר"ן צ״ד:ב׳

12. Now, our Rabbis, of blessed memory, taught: Every person must say: “The world was created for my sake” (Sanhedrin 37a), and he is obliged to improve it. What is its rectification? The matter is as follows: One must see to raise up all the sparks in all things. <As brought elsewhere,> these sparks are letters. Thus we see that one raises up letters, and the letters become words, so that through speech great good is provided to Israel.

2Yet how can a person raise up the sparks to God? The advised course of action is as follows: When a person observes some object, he must immediately believe with complete faith that this object contains letters and sparks. From this faith the zayin is made, as the verse states (Psalms 33:4), “All His acts are done with faith.” The “doing” is the six days of the week, and faith is the seventh, <as is known to those proficient in the mystical tradition>.

3Afterwards, he should combine the faith <with> the wisdom, as it is written (1 Chronicles 28:9), “Know the God of your father.”

4“The God of your father” corresponds to faith, as in: They retain their fathers’ practices (Chullin 13b). We have faith in God, that He is the God of our fathers; this being the main thing. And “know” refers to wisdom and intellect. Wisdom is [the letter] yod, as Rashi explains: “Then Moshe will sing” (Exodus 15:1)—it does not say “ShaR (sang)” but “YaShiR (will sing)”—it is to thought that the Yod refers.

5And from the aforementioned yod and zayin, an ayin is made. This is because in Hebrew letter numerology, zayin times yod is ayin. In addition, the AYiN indicates wisdom, for the wise of the community are called “AYNei (the eyes of) the community” (Numbers 15:24).

6{“You shall make a tzitz (head-plate) of pure gold, u-petachta (and you shall engrave) on it the seal inscription: ‘Holy to God’” (Exodus 28:36).} Automatically, when a person with such an eye looks at something of the world, the sparks certainly ascend. This is as it is written, “You shall make a tzitz of pure gold.” Tzitz connotes looking. When, as mentioned above, it is pure—with faith and wisdom—then “u-PeTaChta on it the seal inscription.” In other words, by means of such an eye, tiPhTaCh (you will open) the sparks sealed in all things and raise them up: “Holy to God.”

7These sparks are letters. The letters become words. And through words, [God] provides great good to Israel. Also, when one raises up sparks from an object, that object then becomes worthless, because they are its life-force.
