Yes I can understand that, feeling 'limited.' I dont foresee that this pack could become a tool I'd use over a period of years, for example, for that very reason (and its a criticism/reservation I have about many modern packs). But its certainly interesting and worthwhile to study it a little, to discover what value it does have.
Flicking through randomly, some of the images evoke my memory of the myths, and I find that interesting and enjoyable because in one simple image you see all the complex associations of the story, with the idea that its also a psychological situation that may sometimes correspond to your own life. So its a little snapshot, like a still from a movie almost, for you to explore. "Hey there's Hercules wrestling the lion!" - etc etc (Strength) - so there's a sense of 'recognition' which is both fun and psychologically interesting.
Felt interested in The Moon this morning, I think for a few reasons. First, I felt recently that an astrological study of the progressed moon is probably very useful and I've never done it (progression basically = the way it moves through your chart over the years). And secondly, I find the image conveys the sense of can't-be-touched depths that control you, not the other way round, quite well. Its the unconscious, the dream-world, the hidden part of you where there's no light so you can't see your way around.
Apart from that, I also read the Mythic book and what it says about moon goddess, Hecate, which is interesting.
