In August 2017, the month that will mark 20 years from Princess Diana's death, Ryuho Okawa used his extraordinary spiritual power (similar to but surpassing Shakyamuni Buddha's) and summoned her spirit for a spiritual interview. This book is a record of the session.

Spiritual Interview with Princess Diana: Her messages, 20 years after her death tells us about the background of the Paris accident and what Diana has been doing since her death. Diana said that through the spiritual conversation, she was able to deepen her understanding on the Spirit World and her own soul, and that she gained the key to return to the world of goddesses in Heaven. This book will provide comfort to many people around the world who mourned Diana's early and unfortunate death, and still admire her beauty and love in their memories. It will also serve as an essential factor in praying for her happiness and glory in the Spirit World.
