Words of Wisdom
The Words of Wisdom (formerly known as the Book of Satori) is an item in Dragon Quest III which allows a character to become a Sage at Alltrades Abbey. The treatise can only be used once, and is found at the Tower of Transcendence.
Satori is a Buddhist term for Awakening, Understanding and (total) Comprehension.
In the official Famicom guide book, the English title of this item is the Book of Understanding.
