The meaning, as far as I know,is not from Beowulf. It was developed
by the four founders and based
off of the ritual of a nearby chapter of a local fraternity. It
parallels the sorority's open motto:

"Ta Kala Diokomen: Let us strive for that which is honorable,
beautiful and highest."

AOT is the abbreviation for the transliterated version of the ancient
Greek:

"Arete opheleo telos: Moral excellence accomplishes our end."

In context, it means that all Kappa Delta sisters should strive for
moral excellence and by doing so they will further the organization
as
a whole. Anyone who is familiar with Kappa Delta knows that they put
great emphasis on Christianity, morals, and being ladylike.
Therefore, moral excellence is the telos or goal/end of Kappa Delta
Sorority. Ask a Kappa Delta if this is true and watch the expression
on her face. Hope this helps and guides you down the correct path.
