Likutei Moharan 76:4/ליקוטי מוהר"ן ע״ו:ד׳

14. This is also the benefit of getting close to tzaddikim. There is an aspect of “My soul thirsts” (Psalms 42:3)—like someone who is so thirsty that he drinks even bad water. The same applies to worshipping God. There are individuals who are always thirsty. They study Torah and constantly serve Him, yet are forever thirsty. This is because although their soul constantly longs to worship God, [their service] is without regularity or intellect. For, occasionally, setting aside Torah preserves it (Menachot 99b), as it is written (Psalms 119:126), “It is a time to do for God; they have abrogated Your Torah.” <They are rectified by> attaching themselves to tzaddikim, who create dimension and time to save these individuals from the aspect of thirst. {“My soul thirsts for God, the living God—O when will I come and be seen in the presence of God?”}

2This is the explanation of the verse: “My soul thirsts for God, the living God”—this is the aspect of thirst, as explained above. “O when will I come” and not be thirsty, “and be seen in the presence of God?” Specifically “and be seen”—i.e., when will I merit service that is in the aspect of seeing? For then it will be with dimension and time, as it ought to be; and so not an aspect of thirst.
