As explained above, the highest blessing Hashem bestowed on the world was the holy Torah. Hashem wrote the five sefarim of Torah, then he created the Neviim and Kesuvim in turn, and attached them to this special blessing, so that when a person speaks words of the Torah, this blessing is bestowed upon him.
Obviously, there are different levels of this blessing, but as long as a person is learning properly, he will always achieve some level of this blessing.
