Likutei Moharan 37:2/ליקוטי מוהר"ן ל״ז:ב׳

12. Now, the body and the soul are corresponding aspects of man and animal, matter and form, wisdom and foolishness; an aspect of light and darkness, as is written (Ecclesiastes 2:13), “as there is an advantage to light over darkness.” And as [our Sages] taught: Great is knowledge for it appears between two signs, as it is said (1 Samuel 2:3), “because the Omnipotent One of knowledge is God” (Berakhot 33a). It is also written (Psalms 118:27), “God is the Omnipotent One, He has given us light”; and it is written (ibid. 82:5), “they neither knew nor understood.”

2[Wisdom and foolishness] also correspond to life and death, as is written (Ecclesiastes 7:12), “Wisdom gives life [to those who possess it]”; and it is written (Job 4:21), “they die, but not with wisdom”; and it is written (Lamentations 3:6), “He made me dwell in darkness.”

3And [life and death] are aspects of forgetfulness and memory, as is written (Psalms 31:13), “I have been forgotten from the heart like the dead”; and it is written (ibid. 98:3), “He remembered His lovingkindness.” And this is what our Sages taught (Avot 3:8): Whoever forgets anything of his Torah lessons, it is as if he bears guilt for his soul, for it is said (Deuteronomy 4:9), “Only beware and watch your soul very carefully, so that you do not forget.”

4And they are an aspect of the Torah’s wisdom. For extraneous wisdom is matter, foolishness, and an aspect of animal vis-à-vis the wisdom of the Torah.
