100 Percent Character

The Rebbe used to tell over that people have a saying regarding shidduchim – that finding the right match means to seek three things: keren tov (a good person), kesef rav (wealth) and yichus (good family pedigree). He explained that actually the percentage of how much importance to attach to each of these three is hinted at by the first letter of each one: keren tov begins with kuf, whose gematria is 100, implying that your search for a chosson with a good character is 100 percent important! Kesef, on the other hand, only requires 20 percent, since it is spelled with a kaf, which has a gematria of twenty. Yichus, which begins with a yud, is only 10 percent important!
