We say in the Yehi Ratzon on Shabbos Mevorchim:
Chaim she'ein bahem busha u'kelima,
Chaim shel osher v'kavod
Chaim she'tehei banu ahavas Torah v'yiras shomayim
Last Shabbos Mevorchim it struck me that these three lines represent the three levels of Talmud Torah:
Al menas l'kanter
The first request is that we should not learn Torah as a tool to embarrass or shame others.
The second request is that we should learn Torah even shelo lishma - for which the reward is b'smola osher v'kadod.
The third request is that we should Torah lishma (orech yamim b'yemina - l'yom she'kulo aroch) - with the approaches and ideals of ahavas Torah and yiras shomayim.
With this approach we can also explain the apparent redundant mention of yiras Shomayim, v'duk.
