When the heart is healthy then the blood in the system reaches all parts of the body. If we understand the general principle, then we can understand all the myriad details. Need to teach the connections from the Chumash all the way to the prohibition of not playing an I-Pod on Shabbos. We are missing the love and respect for halacha (Jewish Law). If we only have little details of our yiddishkeit we become nasty and cranky complainers.
