Hallel: Rosh Chodesh Iyar: Approaching Again: Paragraph Six
Man must initiate all worldly endeavor by first bringing himself close to God, petitioning Him for all his worldly needs. He thus, “casts his burden upon God.” This initiation is crucial for all human effort. When one subsequently engages in various forms of human activity, he is no longer considered to be entangled and immersed in the physical and the worldly. He is supported by this remedy, having initiated all this effort by making it depend on God. He is therefore not lowered by the worldly to nearly as great a degree.
Among God’s acts of love was the fact that He gave man the opportunity to approach Him, even in this physical world. Even though man is immersed in darkness and is far from the Light in his natural physical state, he is still permitted to stand before God and call upon His Name. Man is thus able temporarily to elevate himself from his lowly natural state to exist in a state of closeness to God, casting his burden on Him. (Rabbi Moshe Chaim Luzzatto; Derech Hashem 4:5:3)
