For those who are interested in Buddhism, or are Buddhist, there is:
~ a Japanese booklet “Buddha’s Teachings” which is 36 pages
~ a Japanese hardcover book “The Teachings of Buddha” which is 309 pages
~ a Japanese/English hardcover book “The Teachings of Buddha” which is 609 pages and really cool because it has the English and Japanese on opposite pages. So if you’re struggling to understand a word/phrase/sentence, this can help. Some of the kanji have furigana, some do not.
I have the first and the third.
[Note: Out of respect for the organization providing this for free, you should probably not utilize this if you have zero interest in Buddhism.]
