Psychology and spirituality have a complicated relationship. Dating back to ancient times, we see them treated as sister disciplines which inform and enhance one another. But at some point in the last century, Western psychology decided to divorce itself from Eastern philosophy and spirituality. This left us with an incomplete way of understanding human experience. I take up this story in my new book, Psychology in the Light of the East (Rowman & Littlefield, 2017), and in this interview, we discuss my conviction that our understanding of human nature is best served by attending to the soul as well as to the psyche. I discuss wisdom from Eastern as well as Western traditions and worldviews that back up my point.
