"The Torah is the vitality that is in all things." (Rabbi Nachman of Breslov, Likutey Moharan I, 56)
Comment: The Torah is G-d's name. In the Torah is revealed the nature of the Divine Will, the ultimate goal of creation. Thus, nothing can exist in this world without a spark of Holiness, however small it may be.
Considered practicality, these high concepts mean that we have a duty to inquire about the Divine Will (by studying the Torah, halakhoth ...) and to put this study in our daily actions (by doing mitswoth). Ideally, every minute of our life should be used only to fulfill the will of the Creator.
However, in order to test our Emunah (faith), G-d created us with an evil inclination, whose role is to distract us from the Divine, G-d forbid. Whenever we think or want to get away from the Divine Path, we hear the voice of the evil inclination. If we want to tackle his action, we simply have to pray to ask for help from Heaven. This is the work of our lifetime!
