Parshas HaMon and Emuna in Parnossa

The Perisha in Orach Chaim cites the Yerushalmi that it is a good practice to recite parshas hamon daily. The reason for this segula for parnossa (livelihood) is emuna. The Yismach Yisroel explains that a person may fool himself into thinking that when he works hard and earns a living, "my hard work and my toil is what built this up, and it is my own two hands that created this livelihood and success" (Devorim 8:17). This is an illusion. When a person lacks emuna and is arrogant enough to think that he himself is the source of his financial success, he clogs up his own spiritual plumbing. The pipelines of blessing and shefa (abundance) get clogged from such thoughts. Daily repetition of parshas hamon, however, ingrains in us the truth that it is all really from Hashem, and He is the true source of blessing and parnossa.
