I am not a Buddhist, nor do I have a high degree of knowledge about Buddhism, and perhaps that makes me the perfect target audience for whom ‘The Illustrated Encyclopedia of Buddhist Wisdom’ was written.
The text is basic enough for a lay person to follow and yet it is in-depth enough to still be informative/educational. In addition, the ample amount of color photographs make the book visually interesting and they add to the explanations.
'The Illustrated Encyclopedia of Buddhist Wisdom' starts off with a very brief discussion on the early life of Siddhartha Gautama in India (roughly in 500 BCE), then there is a discussion on: how it spread to various countries in Asia, the underlying principles of Buddhism, the various sects that arose after Buddha's death (specifically Zen Buddhism, Theravada Buddhism and Tibetan Buddhism) and there is also a section on various methods of meditation.
Each of the six chapters is further broken down into smaller headings that allow the reader to gain insights even if the book is not read in a linear fashion. The book comes in at just under 200 pages and the physical book is of high quality.
Overall, I enjoyed 'The Illustrated Encyclopedia of Buddhist Wisdom' because I was able to get a brief overview of Buddhism without being overwhelmed with details and technical information. I realize that those people looking to find very specific information, or those wanting to study Buddhism, will very likely know all of the information contained within this book and they would therefore find the content quite 'rudimentary'.
