it’s always great mussar to really meditate on one powerful line to let the message sink in.
in the past i focused on the end of Koheles, where after exploring how all the earth is empty and devoid of meaning or anything good and worthwhile, the wisest man who ever lived concludes, (in my own words) ‘the end of the matter, all being heard, fear G-d and keep his laws because that is all of man’.
also if you want to focus on learning, remember ‘Torah is our life and the length of our days’
i often focus on the fact that ‘a moment of olam haba is more pleasurable than all of the life of olam hazeh…’
Rabbi Akiva we know focused on the water dripping on the rock and made a hole, and he said to himself if water can make such an impact on solid rock, than Torah which is likened to fire, can make an impact on me and change what i am into something else like the water changed the rock. (it’s a kal vachomer, water which is weak made an impact on something as hard as rock, than Torah, much more powerful than water, can certainly make an impact on man/flesh, which is softer than rock)
