The Value of One Word of Torah

The Alter of Kelm zt”l said that it would have been worthwhile for Hashem to create the world and sustain it for six thousand years just for one Jew to say the words “boruch hu u’baruch shmo” one time. And the recitation of “boruch hu u’baruch shmo” one thousand times does not equal the greatness of one recitation of “amen”. And the recitation of “amen” one thousand times does not equal the greatness of one recitation of “amen yehei shmei rabbah.” And the recitation of “amen yehei shmei rabbah” one thousand times does not equal the greatness of one word of limud haTorah.
