Since Yud-Tes Kislev I've been doing the daily portions of the Tanya and it has been a huge and wonderful infusion of chizuk. This week I got a bit behind but will catch up over Shabbas, G-d willing. I'm also reading Rabbi Adin Steinsaltz's shilta commentary on the Tanya, he's written three books, which cover the first 37 chapters (hopefully he will complete the entire first part) - and he brings much enlightenment to the text.
I don't remember off the top of my head which chapter it apears, but the author discusses how charity is the greatest mitzvah since we invest all our bodies and energy to earn the money we contribute to charity, but if charity is the greatest mitzvah how are we to interpret the words of Chazal that Torah study includes and surpasses all the mitzvot. He explains that charity is the greatest since it involves our total selves and has the power to elevate many areas of the world we inhabit, but Torah study is the greatest since it involves our sechel, and we actually bond with the wisdom of Hashem directly, as opposed to the indirect connecting through charity, or any of the mitzvot of action.
Anyway, that was a long way around to what I wanted to say - which is, that within the discussion of Torah study he brings that Torah study is "calling" to Hashem and he quotes Tehillim, יח קָרוֹב יְהוָה, לְכָל-קֹרְאָיו לְכֹל אֲשֶׁר יִקְרָאֻהוּ בֶאֱמֶת (The LORD is close unto all them that call upon Him, to all that call upon Him in truth). Calling to Him in truth is studying Torah - since Torah is the only truth, and the act of learning Torah is a form of calling to Hashem.
For me, this lesson from Baal HaTanya was an enormous help, and since we say this pasuk three times daily, it will serve as a constant reminder of the power of Torah study.
