Musar su Salmi 102:27

And therefore David said (see Lev. Rabbah 4:8), just as the soul fills the body and carries the body and outlives the body and is unique in the body and does not eat things of the body, sees and is not seen, and is pure within the body and does not sleep, so does the Holy One, Blessed be He, fill His world, as it is said, "Do not I fill heaven and earth? saith the Lord" (Jer. 23:24). And He bears His world, as it is said, "I have made, and I will bear; Yea, I will carry and will deliver" (Is. 46:4). And He outlasts His world as it is said, "They shall perish, but thou shalt endure" (Ps. 102:27). And He is alone and unique in His world, as it is said, "Hear, O Israel, the Lord our God, the Lord is One" (Deut. 6:5). And eating does not apply to Him, as it is said, "Do I eat the flesh of bulls, or drink the blood of goats?" (Ps. 50:13). And He sees and is not seen, as it is said, "Which are the eyes of the Lord, that run to and fro through the whole earth" (Zech. 4:10). And He is pure in His world, as it is said, "Thou that art of eyes too pure to behold evil" (Hab. 1:13). And He does not sleep as it is said, "Behold, He that keepeth Israel doth neither slumber, nor sleep" (Ps. 121:4). Therefore the soul which has within it all these qualities should come and praise the Holy One, Blessed be He, Who has within Himself all these qualities.
