The Natural Love of the Soul
"If you continually hearken to My commandments that I command you today, to love HaShem..." Is "to love HaShem" the sum total of what HaShem requires of us? Aren't there six hundred and thirteen commandments?
King David said "My soul knows very much" (Tehillim 139:14), meaning, the human soul is inherently wise, i.e., it knows HaShem. However, the material element of the body intercepts our inner light. Therefore, HaShem gave us the Mitzvoth, which protect the soul from the impure influence of the material elements.
Lesson: The purpose of Torah is to preserve the holiness of our soul. As long as the soul is protected through Mitzvah observance, it naturally is drawn to its source. Hence, it is filled with love for its Creator.
Visualization: Envision your soul attaining its natural state of purity and loving HaShem, through Mitzvah observance. [Based on Da'as Torah of Rabenu Yerucham HaLevi]
