I discovered this relatively simple way of adding a embedded summary of a note that links to itself for embedding in other notes. Which can be useful as a quick reminder of something without bringing up the entire note.
Here is the code for the note:
## [[Example Page#B|Title ]]
### This is the optional embedded display heading.
This is the embedded display body. Everything here will be shown when you embed using
`![[Example Page#Example Page B Title]]`.
#
%%Everything above the # is the embedded display.
%%
--------------------------
# %%B%%
## This is a optional heading. It must be heading 2 or smaller
This is the main body of the page. This is not shown in the embedding
### add as many headings as needed
