Someone once asked R’ Chaim Pinchos Scheinberg zt”l why he had such extraordinary self-sacrifice for the mitzvah of tzitzis. He answered very simply, “Chacham lev yikach mitzvos” – the wise of heart will seize good deeds (Mishlei 10:8). He would often cite the Gemara, “Grab and eat, grab and drink, for the world which we are leaving is like a wedding” (Eruvin 54a). He wanted to chap as many mitzvos as he could. When he was asked how he could wear so many pairs when they were so heavy, he would respond, “Would you have such a question if you were carrying gold?” To him, his layers of tzitzis were layers of pure gold.
