I have finished reading this, but I have started at the beginning again and am often flipping through it to re-read parts. I wish my brain worked well enough that I would have it memorized and completely absorbed in one reading, but that is not the case. I have also started reading parts of it to my weekly Tehillim group. It is very well liked by everyone there.
Rabbi Raskin tells us what the particular shape of each letter represents, what the gematria is and what that means, and what the particular meaning of the word is. It is fascinating, eye-opening and awesomely inspiring.
Highly recommended.
