Make it a property:

#+PROPERTY: magic abbracadabra

#+begin_src emacs-lisp :var value=3D(org-entry-get (point) "magic" t)
value
#+end_src

#+RESULTS:
: abbracadabra


When you add/change a  property like this be sure to update (C-c C-c on the=
 PROPERTY line or save, close, open the file).

For a long string, you might put it in a src block and then use :var value=
=3Dblock-name() to get it.
