This is a unique book, drawing together the profound insights of Eastern philosophy Advaita Vedanta, Western depth-psychology Jungian, and spirituality Ignatian as applied to decision-making. Mention is made of Plato, C. G. Jung, Ira Progoff, Viktor Frankl, and Bernard Lonergan, amongst others. Powerful and practical tools and techniques for making wise decisions are offered. There are sections on Descartes's famous square, the ego and the Self, the I Ching and synchronicity, archetypes, neuroscience and the triune brain, biases and blind spots which can derail decision-making, together with chapters on creativity, the aha experience, and the Enneagram with its nine decision-making styles. Dr. Costello is at pains to point out that heart emotions, head reason, and hands actiondoing must be integrated before effective decision-making can take place and bear fruition.
