As far as I known this has to be ordered from the Shingon International Institute directly (Amazon prices are wonky because there are so few copies in circulation), ref: http://www.shingon.org/sbii/books/ShingonHBF.html
I was tempted to buy a stack and become a reseller.
There are a few lay service guides (essentially daily gongyo guides):
e.g.http://shingonjitemple.org/wp-content/u ... der-11.pdf
If I remember correctly, there are only a few rites that you can do without empowerment (meditation on the syllable "a", etc), but if you look, you can track down PDFs describing the gist of the rest of the Shingon rituals-- most of which are written by academics. Sharf's "Thinking Through Shingon Ritual" -- http://archiv.ub.uni-heidelberg.de/ojs/ ... /8931/2824
-- it is fascinating but doesn't provide enough detail to "break the rules" and do rituals own your own.
If anyone else finds a PDF, please post. My searching of google didn't turn up anything, I suspect this particular book has never been converted to PDF or other ebook format.
