Those wishing to ascend the ladder of holiness must begin their journey with the study of Torah. It is the Torah that tells us what we should be watchful about. How do we know what to refrain from and what is bad for us? The Torah teaches us.
Imagine a person who would develop a sickness and then also prepare the cure for it at the same time. Imagine if he were to tell people that in addition to the sickness, he knows of its cure and instructs that it is the only way to heal.
So too God has created the sickness – the evil inclination, and He has also created the cure – the Torah. Who would choose to ignore the cure when it is clear that it is the only one that works?
Those who wish to rid themselves of the negative and evil that prevents us from ascending in holiness should listen well to the advice of the Ramchal at this point. Our first step is to engage in Torah study – the healing pill for keeping ourselves away from what is not for our good – and the healing pill that will ultimately bring us onto a path of goodness and holiness.
