Opening the Heart of Compassion is one of only a few (and the best imo) English language expositions on the Buddhist model of human psychology and I found it enormously illuminating and applicable. Many get put off by the first section which has a bunch of stuff about Tibetan Buddhist deities, but the sections on the realms in part two are amazing. It also very briefly touches on a transformative practice called aspirational inquiry about investigating your own motivations. It seems to have been independently discovered by Connierae Andreas and is the subject of her book Core Transformation.
