Tanya, Part I; Likkutei Amarim 9:1

Hook

This passage from Tanya’s Likkutei Amarim doesn't just describe the two souls within us; it locates them, physically mapping their battleground onto the human body, specifically the heart and the brain. What's non-obvious is how deeply this spiritual dichotomy is tied to our very physiology, suggesting that our internal conflicts have a tangible, anatomical basis.

Context

To grasp the weight of this anatomical mapping, consider the prevailing philosophical and medical thought of the time. While Maimonides, a towering figure in Jewish philosophy and law, extensively discussed the soul and its faculties, his approach was largely abstract and intellectual. The Tanya, written centuries later, is deeply rooted in the Kabbalistic tradition, which often sought to find immanence and tangible expression for spiritual concepts. This passage, by assigning the "divine soul" to the "brains" and the "animal soul" to the "heart" (specifically its blood-filled left ventricle), is a profound move towards psychosomatic understanding, predating modern psychological and physiological correlations. It's a bold assertion that our spiritual striving is not just a mental exercise but a visceral, physical struggle.

Text Snapshot

"The abode of the animal soul ( nefesh habahamit), derived from the kelipat nogah in every Jew, is in the heart, in the left ventricle that is filled with blood. It is written, “For the blood is the nefesh.” (Deuteronomy 12:23). Hence all lusts and boasting and anger and similar passions are in the heart, and from the heart they spread throughout the whole body, rising also to the brain in the head, so as to think and meditate about them and become cunning in them... But the abode of the divine soul is in the brains that are in the head, and from there it extends to all the limbs; and also in the heart, in the right ventricle wherein there is no blood, as is written, “The heart of the wise man is on his right.” (Ecclesiastes 10:2)."

"It is written, however, “One nation shall prevail over the other nation.” (Genesis 25:23). The body is called a “small city.” (Ecclesiastes 9:14; Nedarim 32b). Just as two kings wage war over a town, which each wishes to capture and rule, that is to say, to dominate its inhabitants according to his will so that they obey him in all that he decrees for them, so do the two souls—the Divine and the vitalizing animal soul that comes from the kelipah—wage war against each other over the body and all its limbs."

"Thus it is written, “‘With all your heart’—with both your natures.” (Deuteronomy 6:5). That is to say that the person shall steadily rise to attain to the degree of “abundant love,” a supreme affection surpassing that of “ardent love” that is comparable to burning coals."

"Thus it is written in Etz Chaim, Portal 50, ch. 3, on the authority of the Zohar, that the evil is converted into, and becomes, completely good, like the good nature itself, through the shedding of the soiled garments, the pleasures of this world, in which it had been clothed."

Insight 1: The Dual Topography of the Soul

The most striking structural element is the explicit physical mapping of the two souls. The animal soul, associated with primal drives and the sitra achara (the "other side" or negative spiritual realm), is firmly rooted in the "heart, in the left ventricle that is filled with blood." This is no accident; the Tanya connects this directly to the biblical verse "For the blood is the nefesh" (Deuteronomy 12:23), linking the life force and its desires to the physical medium of blood. From this visceral core, its influence "spread[s] throughout the whole body, rising also to the brain." Conversely, the divine soul finds its primary "abode... in the brains that are in the head," extending outward to the limbs, and also residing in the "right ventricle" of the heart—the side described as devoid of blood and associated with wisdom ("The heart of the wise man is on his right," Ecclesiastes 10:2). This dual topography establishes a physical basis for the internal spiritual struggle, framing it as a conflict for control over the body's organs and faculties.

Insight 2: The Key Term: Nefesh HaBahamit and its Genesis

The term "nefesh habahamit" (animal soul) is central here, and its origin in "kelipat nogah" is crucial. Kelipat nogah is a complex Kabbalistic concept, often translated as "peel of brightness" or "shell of light." It's a semi-holy realm, distinct from the purely negative kelipot (husks or shells). Nogah acts as a mediator: it contains elements of both holiness and impurity. The animal soul, deriving from this realm, is thus not inherently evil but possesses a potent capacity for desire, passion, and self-interest that can easily be directed towards baser pursuits. The Tanya clarifies that this soul is responsible for "lusts and boasting and anger and similar passions." Its physical manifestation in the blood-filled left ventricle underscores its connection to life, vitality, and immediate gratification, making it a powerful, yet potentially misguided, force within the human being.

Insight 3: The Tension: War for the "Small City"

The core tension of this passage lies in the declared "war" between the two souls, conceptualized as two kings vying for control of a "small city"—the body. This metaphor, drawn from Ecclesiastes and the Talmud (Nedarim 32b), highlights the high stakes of this internal conflict. The divine soul's desire is for complete dominion, for all limbs to become "a vehicle... as well as a robe" for its divine faculties. The animal soul, conversely, seeks to dominate through its passions. The passage climaxes with the powerful declaration, "'With all your heart'—with both your natures," referencing Deuteronomy 6:5 and the rabbinic interpretation in Berachot 54a. This phrase encapsulates the ultimate goal: not the eradication of the animal soul, but its transformation and integration. The tension is between the potential for subjugation by the animal soul's desires and the aspirational sublimation of these very desires into holy service, a process described as converting "evil [into] completely good."

Two Angles

Angle 1: Rashi's Focus on Literal Interpretation and Practicality

Rashi, the quintessential medieval commentator on the Torah, often prioritizes a straightforward, literal understanding of the text and its practical implications for Jewish life. If Rashi were to engage with this passage, he would likely anchor his interpretation in the biblical verses cited. For instance, "For the blood is the nefesh" (Deuteronomy 12:23) would be understood as a direct physiological correlation, informing the prohibition of consuming blood. He might see the "heart of the wise man is on his right" (Ecclesiastes 10:2) as a metaphorical description of clear, rational thought versus the clouded judgment associated with excessive emotion. Rashi's focus would likely be on how these concepts inform ethical behavior and mitzvah observance, emphasizing the need for self-control to align one's physical impulses with divine will. The anatomical specificity in Tanya would be seen less as a Kabbalistic map and more as a vivid illustration of the well-known struggle between inclination and obligation.

Angle 2: Ramban's Mystical and Moral Exegesis

Nahmanides (Ramban), on the other hand, was deeply influenced by Kabbalistic thought and often layered mystical interpretations onto biblical texts. Engaging with this Tanya passage, Ramban would likely embrace the concept of the two souls as distinct spiritual entities with profound implications for human destiny. He would see the "left ventricle" and "right ventricle" not just as anatomical locations but as symbolic centers of spiritual influence. The battle described would be interpreted as the ongoing struggle for the soul's ultimate allegiance between the forces of holiness and impurity. Ramban might emphasize the Zohar's ideas about the transformation of negative forces, seeing the Tanya's concept of "converting evil into good" as a key to spiritual ascent. He would highlight the divine soul's struggle to permeate the entire being, making the body a "garment" for holiness, a journey he would frame within a broader mystical framework of divine immanence and human participation in the cosmic order.

Practice Implication

This passage fundamentally reframes how we approach our internal struggles. Instead of viewing negative impulses—anger, lust, arrogance—as simply moral failings, Tanya presents them as manifestations of the animal soul, physically located and energetically driven. This understanding offers a pathway for action beyond mere suppression. When faced with a negative inclination, rather than just feeling guilt, we can recognize it as an expression of the nefesh habahamit emanating from the left ventricle. The implication for practice is to consciously engage the divine soul located in the brain. This means actively using our intellect and wisdom (chabad) to meditate on divine greatness, to cultivate awe and love for God, and to direct these higher affections to "inundate the left side as well, to the extent of subduing the sitra achara." It's a call to actively redirect the body's energy, transforming the "blood" of desire into the "water" of divine love, as the text suggests. This isn't about fighting an abstract evil, but about harnessing and transforming specific physical and emotional energies through intentional spiritual practice.

Question 1: The "Small City" Dilemma

The body is described as a "small city" fought over by two kings. If the divine soul desires complete dominion, and the animal soul desires to rule according to its will, what is the ethical tradeoff in fighting to exclusively subjugate the animal soul versus the Tanya's ultimate goal of transforming it? Does absolute victory over the animal soul risk diminishing the very "city" that is meant to be inhabited by holiness?

Question 2: The Nature of "Abundant Love"

The text distinguishes between "ardent love" (like burning coals) and "abundant love" (ahavah rabbah), which is associated with "delights" and the World to Come. If the divine soul's primary abode is the brain, and its influence extends to the heart, how does one reconcile the fiery passion of ardent love with the serene, intellectual delight of ahavah rabbah? What is the practical challenge in cultivating a love that is both intense and profoundly peaceful?

Takeaway

This passage teaches us that our internal spiritual warfare is a deeply embodied process, a tangible conflict for control of our physical being, where transformation, not just suppression, is the ultimate spiritual victory.
