The Soka Gakkai Dictionary of Buddhism

This dictionary occupies a distinctive position among English-language Buddhist reference works. Rather than presenting Buddhist terminology solely from one ancient linguistic canon, it brings together Indian, Chinese, and Japanese Buddhist vocabulary and places considerable emphasis on the historical transmission and interpretation of Mahāyāna Buddhism.

Its strongest thematic concentration is on Nichiren Buddhism and the Lotus Sutra. The editors explicitly explain that many entries were selected because they assist readers in understanding Nichiren’s writings, while also including concepts necessary for a broader understanding of Buddhist history and philosophy. 

Although the dictionary encompasses a broad range of Buddhist materials, its principal editorial orientation is closely connected with Nichiren Buddhism, the Lotus Sutra, and the writings of Nichiren. At the same time, it introduces important concepts from the wider development of Buddhism, including doctrines and traditions originating in India and subsequently transmitted throughout Central, East, and Southeast Asia. Entries address Sanskrit and Pāli terminology, Chinese and Japanese Buddhist names, major Mahāyāna concepts, historical teachers, scriptures, doctrinal schools, and important events in Buddhist history.

A significant feature of the work is its attention to linguistic and terminological clarification. The editorial guide explains conventions for Sanskrit and Pāli romanization, Chinese and Japanese names, proper names, translated Buddhist terms, chronological information, and cross-referencing. This makes the dictionary particularly useful for readers encountering Buddhist vocabulary across several linguistic traditions. 

The main alphabetical dictionary is supplemented by reference materials covering Sanskrit and Pāli terms, Chinese proper names, Buddhist documents, schools, maps, Chinese dynasties, and Japanese terminology. Overall, the volume functions as both a practical Buddhist lexicon and a reference guide to the doctrinal and historical world in which Nichiren Buddhism developed.
