Musar su Geremia 4:7

He prayed for the דבקות to become manifest already before the conquest of the land of Canaan. As long as Israel carries out G–d's wishes this affinity exists, and the name of G–d as well as the throne of G–d is complete. When Israel sinned with the golden calf, one of the four supports of G–d's throne, i.e. the פני השור, "slipped," causing G–d's throne and His name to become impaired. As long as Israel carry out G–d's desires, they are the carriers of the Presence of G–d, they serve as the throne. As long as such a situation continues they are called אדם, i.e. they represent the פני אדם mentioned in Ezekiel's vision as one of the four carriers of G–d's throne (Ezekiel 1,10). The study of the Torah is one leg of the four legs supporting G–d's throne, the one called פני השור. This is based on ורב תבואות בכח השור (Proverbs 14,4). Our sages have said that one should apply oneself to Torah study as an ox applies himself to the yoke (Avodah Zarah 5). When it comes to the practical performance of what is written in the Torah one should behave like a lion and an eagle, as we know from Rabbi Yehudah ben Teyma in Avot 5,20. The Rabbi refers to the sharp eye possessed by the eagle and the courage possessed by the lion, a function of the heart. The Torah itself warns us not to allow our eyes and our hearts to make us stray from the path of Torah (Numbers 15,39), evidence that these two organs are of prime importance in carrying out G–d's commandments. Should Israel fail to live up to these obligations, also these two legs of G–d's throne would collapse.
