But even when God is hidden in הסתרה שבתוך הסתרה "hidden-ness that is hidden," it is still possible to reveal the presence of God when one seeks Him. You seek God by Torah. Torah is the interface between God and his creation. This inserts an intermediate step that you don't have in Schopenhauer.
With Schopenhauer there is only the Will (the thing in itself, the dinge an sich) and the entire creation is the representation of that Will (i.e. conditioned reality).
Torah is the Representative of God and the creation being the representation of Torah. . For it is the open aspects of Torah that are represented in the world. But it is the hidden aspect of the Torah that is contained in the hiding of the hiding.
The idea here is that God has an interface with the world. Torah is that interface. That is the Written Torah and its explanation that was written down by the Tenaim and Amoraim. [That is like how you interact with your hard drive. You need some interface in order to do so.]
What I suggest then is a yeshiva in which the Oral and Written Torah are learned and practiced. But the Torah learned has to be authentic. Way too many pseudo yeshivas exist. I can count the real yeshivas in the entire world on five fingers. Three in NY: Mirrer, Chaim Berlin, Torah Vedaat. And two in Israel: Ponovitch and Brisk. Most so called "yeshivas" are actually evil cults.
