It is because when you open bash from Emacs bash is
the interactive shell. When you open Emacs from bash
Emacs talks to a non-interactive bash where BASH_ENV
is the only thing that is sourced. (Or so I've heard -
I don't use bash myself - I use zsh, where you solve
this by putting shared stuff in .zshenv)

So try putting the shared file path in BASH_ENV, or
you can even try:

    BASH_ENV=~/.bashrc emacs

The the distinction interactive/non-interactive gets
foggy but I suppose your computer won't blow up.

Indeed, the material is not read is the problem.

Yes, you can do that.
