Perhaps the following will illustrate the idea of chibuv for lavin:

Rashi, Vayikra 20:26: Rabbi Elazar ben Azaryah says, "... One should 
not say 'I am disgusted by pork' or 'I don't like wearing shaatnez'. 
Rather, he should say, 'I *DO* want it, but what can I do? My Father 
in Heaven decreed for me not to.'"

Granted, there is no action or object here (comparable to peyos or 
the esrog box), but chibuv is an *attitude*, a *feeling* which goes 
above and beyond the mere "shev v'al taaseh" passiveness of avoiding 
the action whichj the lav forbids. And R Elazar ben Azarya clearly 
went out of his way to have such an attitude.

(BTW, it took me a long time to find that quote, because I thought it 
was Rabbi Akiva's saying. Anyone know if there's someplace where R 
Akiva says this same idea?)
