It is well known that Reb Aharon once said that a kal she’bkalim is one who collects kulos until he has the maximun kulos on everything – he is a kal she’bikalim.
The opposite of a kal she’bikalim is one who collects chumros. The more chumoros one has the more he is choraid lidvar Hashem. One who acts lifnim mishuras hadin is also treated that way min hashomayim.
May we have more chumros than kulos. That is what Hashem wants from us. Ezehu chosid, hamischasid im kono!
