Core Beliefs – יְסוֹדוֹת הָאֱמוּנָה

We are forbidden to stray after the desires of the heart or the sights of the eyes.

This mitzvah prohibits indulging imagination and desire apart from Torah’s guidance. Rambam (Hilchot Avodat Kochavim 2:3) explains that following the heart leads to heretical thought, while following the eyes leads to immoral acts. Sefer HaChinuch (Mitzvah 387) emphasizes that this mitzvah trains self-control, ensuring one’s passions serve Torah, not oppose it.

The Talmud (Berachot 12b) ties this mitzvah to the command of tzitzit, teaching that looking at tzitzit prevents straying. Rashi interprets “heart” as heresy and “eyes” as lust. Ramban adds that the command protects against idolatry, immorality, and arrogance. Midrash (Sifrei Shelach 115) comments that Torah warns against curiosity leading to sin, paralleling Eve’s temptation by the Tree of Knowledge.

Commentary & Classical Explanation:

  • Rambam (Avodat Kochavim 2:3): Heart leads to heresy, eyes to immorality.
  • Sefer HaChinuch (387): This mitzvah cultivates discipline and purity.
  • Talmud (Berachot 12b): Tzitzit prevent wandering of eyes and heart.
  • Rashi (Num. 15:39): Heart = heresy, eyes = lust.
  • Ramban: Warning against idolatry and arrogance.
  • Midrash (Sifrei Shelach 115): Temptation begins with eyes and heart.

Contrast with Inquiry into Idolatry (Mitzvah 24):

  • Mitzvah 24 forbids turning thoughts toward idols.
  • Mitzvah 25 forbids straying after personal desires.
  • Rambam notes one protects against external corruption, the other against internal weakness.

Parallel to Tzitzit (Mitzvah 84):

  • Tzitzit serves as a safeguard against straying eyes.
  • Talmud (Menachot 43b) connects this mitzvah to tzitzit directly: “Look at them and remember all My commandments.”
  • Ramban comments that mitzvot like tzitzit anchor the heart and eyes in holiness.

Applying this Mitzvah Today

Guarding Thought and Desire

  • Rambam (Hilchot Avodat Kochavim 2:3) interprets this mitzvah as forbidding mental wandering into heresy and unbridled desire. Today, this means cultivating mindfulness over what we consume intellectually and visually — resisting ideologies or images that draw the heart away from Hashem.

Discipline in an Age of Distraction

  • Sefer HaChinuch (Mitzvah 387) writes that human desires, if unchecked, pull a person toward sin. In our era of constant digital temptation, this mitzvah calls for discipline — setting filters, practicing restraint, and creating environments that foster holiness of thought.

Sanctifying the Eyes

  • Talmud (Berachot 12b) explains that “heart” refers to heretical thoughts and “eyes” to sexual temptation. Applied today, this mitzvah means guarding against immodest media, pornography, and consumerist imagery — preserving dignity and sanctity.

Strengthening Faith in Modernity

  • Ramban (Num. 15:39) stresses that this mitzvah prevents straying from Torah when surrounded by foreign philosophies. In an age of secularism, materialism, and relativism, it challenges Jews to remain loyal to Hashem and Torah values.

Building Inner Awareness

  • Midrash Tanchuma (Shelach 15) warns that the eyes and heart are “spies” for the body. Today, this mitzvah urges self-awareness: recognizing which influences elevate us and which degrade us, and choosing paths that align with holiness.

Embedding in Daily Life

  • The mitzvah is tied to tzitzit, reminding Jews daily “not to stray after your eyes and your heart.” Wearing tzitzit today remains a powerful spiritual practice — a physical anchor of the mitzvah amidst a culture of distraction.

Notes on this Mitzvah's Fundamentals

Faith – אֱמוּנָה

  • Rambam (Avodat Kochavim 2:3) warns that heretical thoughts begin by following the heart. Sefer HaChinuch (387) explains that emunah requires controlling thoughts as much as deeds. Talmud (Berachot 12b) ties faith to vigilance over heart and eyes, reminding us that unchecked imagination erodes belief.

Core Beliefs – יְסוֹדוֹת הָאֱמוּנָה

  • Ramban identifies this mitzvah as safeguarding Torah’s foundations: belief in Hashem’s unity, truth, and providence. Midrash (Sifrei Shelach 115) interprets straying as abandoning core tenets of Torah. Rashi highlights that “heart” = heresy shows this mitzvah protects against theological error.

Reverence – יִרְאַת שָׁמַיִם

  • Talmud (Menachot 43b) says tzitzit remind Israel of awe of Heaven, restraining wandering eyes. Rambam notes that reverence demands discipline of thought. Midrash connects this mitzvah to yirah, since it compels awareness that Hashem sees inner and outer conduct alike.

Holiness – קְדֻשָּׁה

  • Ramban (Lev. 19:2) defines kedushah as sanctifying desires. Sefer HaChinuch teaches that refraining from forbidden thoughts elevates the soul. Midrash Rabbah (Bamidbar 17:5) connects holiness to guarding eyes, since the eye is the “gateway to the soul.”

Thought – מַחֲשָׁבָה

  • Rambam says imagination is the root of sin if left unchecked. Talmud (Sanhedrin 63b) explains that sin begins in thought. Midrash likens the eye and heart to spies for the body, warning that undisciplined machshavah misleads one from Torah.

Love – אַהֲבָה

  • Rambam (Teshuvah 10:6) writes that true love of Hashem demands inner loyalty, not only outward observance. Talmud (Sotah 14a) says imitating Hashem’s ways begins with aligning desire toward Him. Rashi on the Shema connects love with directing both heart and eyes toward Hashem alone.

Bein Adam L’Makom – בֵּין אָדָם לְמָקוֹם

  • Ramban explains this mitzvah is wholly between man and G-d, guarding loyalty in unseen places. Midrash teaches Hashem desires the heart, not only deeds. Rambam affirms this mitzvah as cleaving to Hashem internally, restraining impulses that estrange one from Him.
