The conventional way to define your own commands is to use :command.
See
:help 40.2
Your command would be defined like this:
:command Vimrc e ~/.vimrc
User-defined commands must start with an upper-case letter. There
are ways around this limitation, but since you're a newbie, I think
it's best to stick with the basics for now.
The reason your cmap caused an infinite recursion is because the lhs
of the mapping was part of the rhs. When Vim discovered the "vimrc"
in the rhs it knew it had a mapping with that lhs and executed it.
To avoid that problem, use cnoremap instead of cmap. See
:help 40.1
and search for "^REMAPPING".
