Based on the words of Ramban, we need to consider why we require the 613 commandments, including the commandment of studying Torah. After all, if the primary purpose of a person is faith in God and giving thanks to His name, why wouldn't it suffice for a person to dedicate all their time to contemplating faith, beholding the beauty of God, and praising Him, giving thanks, and recounting His glory?

In simple terms, the answer is that without studying the Torah and observing the commandments, it is impossible to achieve complete and clear faith. Only after a person's mind is straightened and their character traits are corrected through the study of Torah and the observance of its commandments, does the person become capable of understanding and believing in the truth and honesty of faith: that there is a Ruler of the universe who created, formed, and perfected it, and that it is fitting to give thanks to His name and recount His praise. However, without proper understanding and the correction of character traits, a person's mind is confused and corrupt, and their traits are bad. Both together blind their eyes from seeing and prevent them from understanding in their heart. Thus, the person is not capable and does not have the ability to achieve clarity of thought and to grasp the truth of the matter.

Indeed, a careful examination of Ramban's words reveals that even more depends on the unique quality of the Torah and its commandments. For he wrote: "The purpose of all the commandments is that we believe in our God and give thanks to Him for creating us." This means that their benefit is not only in preparing and correcting a person's soul to be capable and corrected for acquiring faith and the desire to give thanks, through the means provided for this purpose. Rather, the commandments themselves and their very observance bring about faith in God and gratitude to His name.

We learn an essential principle from this: that even the observance of the commandments is not an end and purpose in itself, but a tool and a reason to bring us to faith in the Blessed God and to give thanks to Him.
