Kukai, or also known as Kobo Daishi (the Great Propagator) continues to be one of the most respected Japanese throughout the history of Japan. He was the founder of Japanese Shingon Buddhism, a form of Vajrayana Buddhism that He learned in China, was titled the Master of Five Brushes (Master Calligrapher) and was known for his public works projects and the founding of Mount Koya, The Center of Shingon Buddhism. This Book by Dr. Yasutoshi Murakami explains in modern language the depth of Kukai's words. They are words that are ageless based on the mind of an intellectual master. Kukai brought and developed esoteric buddhism (Mikkyo) to Japan in 806 CE. It remains almost unchanged for the last 12 Centuries. The words, rituals, and Shingon Path are as fresh Today as they were when first brought to Japan. If one wishes to understand Japan this is a good beginning for these words touch at the heart and foundation of Japanese Culture.
