How it's used
Originally referring to a mythical book from heaven, this term is now used to describe any resource that provides essential, insider knowledge or shortcuts. It is frequently used in academic or professional contexts to describe study guides or manuals that contain all the necessary information to succeed. It implies that the content is highly practical and almost magical in its ability to solve problems.

Common mistake
Do not confuse this with a literal book from heaven, as the term is almost exclusively used metaphorically to describe helpful guides or cheat sheets. It is also not used to describe standard textbooks, which are usually just called 書.
