The Kuzari was told in a dream, “Your intentions are desirable, but your deeds are not.” R’ Yosef Yozel Hurwitz zt”l posed a question: We, too, seek the truth.  Why do we not have dreams in which God reveals to us whether our deeds are desirable?

The answer is that the Kuzari was searching for truth in order to act upon it.  We, however, seek truth merely for the sake of seeking.  We fail to act even on the truth that we are aware of.  So Divine clarification would be wasted on us.  ~ Sparks of Mussar
