Musar su Salmi 115:16

Midrash Kohelet adds that the ultimate purpose of Torah is that its teachings be performed in practice, as we know from the statements of our sages in Kidushin 9 that "study is great since it leads to performance." Similarly, at the time when the idea of creation was conceived the realization of its ultimate purpose was in G–d's mind. This purpose was the creation of man, not of the ministering angels. The Torah was not given to the latter, seeing that they are not physical creatures. Only someone who is an integral part of this earth is able to perform the commandments of the Torah. The angels themselves admitted this when they are quoted as saying in Psalms 8,2: "O Lord, our G–d, How majestic is Your name throughout the earth, You who have covered the heavens with Your splendor!" [according to the interpretation of the Talmud Shabbat 88 this was said by the ministering angels. Ed.] The same thought is expressed in Psalms 115,16: "The heavens belong to the Lord, but the earth He gave over to man." The "earth" referred to in that verse is the Earth of a higher world in which the כנסת ישראל is rooted, since the name of G–d א-ד-נ-י, is the root of Israel; I have explained elsewhere, that the emanation מלכות is the uppermost level of the physical world, beyond which there is only a world of thought. Before creating man G–d took "dust" [raw material Ed.] from all the various worlds including parts which to us are known as "heaven," i.e. Torah, and "earth" i.e. Israel.
