I will admit, these cards were a bit difficult to get into, only because each card has so many references specific to Hawaiian culture that would not be obvious unless you had a Ph.D on the subject, so do expect to be reading the reference booklet often. However, the booklet is seriously like reading a storybook: it has background information on the main themes of the card, a Hawaiian chant, as well as the card's interpretation. The wording makes you feel like you're being told advice from your great Hawaiian grandmother. There really is an immense amount of wisdom contained in the booklet alone, and I guarantee you that, as you read for others, you'll learn that a lot of the Hawaiian wisdom can apply to your own daily life.
As a reader, I use this deck mainly for "soul journey" questions, such as "Am I on the right path for my career?", "What is my soul purpose?", "What do I need to know about this future situation?", etc. My clients have loved the images and deep messages that I've relayed to them from these cards.
Overall, it's a very enlightening deck that's sure to teach you a lot about yourself and the most down-to-earth way of life from the native Hawaiians' perspective.
