Benefit Beings!: The Buddhist Guide to Professional Chaplaincy by Danny Fisher. USA, Off the Cushion Books, 2013. (ISBN 978-0615-796499)
"Benefit Beings!" was written to help Buddhists engaged in professional chaplaincy work in North America, and those who wish to join their ranks. The book is organized into several chapters, each offering a brief history of a particular chaplaincy (with special attention on relevant events for Buddhists); an explanation of the requirements for service as a professional chaplain in that field (again, with an understanding that the intended reader is a practicing Buddhist); and an examination of the work done by Buddhists in that chaplaincy (including positions held, scholarship produced, and so on).
The book includes information on the only known Buddhist Fire Department Chaplain in the USA, Rev Alan Urasaki of Hawai'i on pages 18-19, 142-43, 147, 150-51. Danny Fisher states on page 151 "Rev. Urasaki also appears to be the only Buddhist Fire Chaplain in the country: in 2004 he was appointed as a volunteer Chaplain with the Honolulu Fire Department".
