There seem to be lot of opinions about "What Torah is all about." The Musar opinion of Isaac Blazer [good traits and fear of God] is not the only one. There is Abraham Isaiah [author of the חזון איש] that the main thing is to be careful about law. The commentary on the beginning of Mishne Torah of the Rambam holds the main thing is to come to the higher awe of God. The Ran of Breslov held it is שמירת הברית [sexual sanctity]. The Torah itself puts a lot of emphasis on coming and staying in Israel in Deuteronomy פרשת היראה.
I think the higher awe of God is certainly among the major goals of Torah. But I can also see that Rav Isaac Balzer was right because I see most of the books of the great sages of the Middle Ages and also the Reshash [Rav Shalom Sharabi] seconded his motion.
The opinion that the ultimate purpose of Torah is to come to awe of God has an important practical application. For if one merits to this awe of God, he might be tempted to push it off by ignorence of its value. So simply being aware of this idea is important.
The approach of the Gra and his disciple Reb Haim of Voloshin is that the major way of coming to Oneness with God and Awe of him is by learning Torah. This idea is in fact mentioned openly in the Yerushalmi Gemara in Peah.כל חפציך לא ישוו בה. כל חפצים לא ישוו בה אפילו חפצי שמיים אינם שווים לדיבור אחד של תורה All the commandments are equal to even one word of learning Torah.
[This idea of the Gra I think is quite right.]]
