What is the meaning of "Garsah"?
Rashi: My Nefesh is broken due to desire 1 . This is like "Geres Karmel."
Malbim: It is a command and request to remove the outer shell from his Nefesh - physicality that covers it, and it is distracted in its matters.
Radak: To learn Your Mishpatim at all times, even when I engage in worldly matters.
What is the meaning of "l'Sa'avah [El Mishpatecha]"?
Rashi, citing Menachem: This is like "Mesa'ev Anochi Es Ge'on Yakov." Also this is an expression of breakage.
Radak: It is Makor (like an infinitive), like "Ta'avti li'Yeshu'asecha Hashem" (174), i.e. desire.
Malbim: Physicality blocks the Nefesh from desiring Hashem's Mishpatim, which are to remove injustice and theft. Physicality desires these! "Simchah la'Tzadik Asos Mishpat u'Mechitah l'Fo'alei Aven" (Mishlei 21:15) - after its shell of physicality is removed.
