It contains hyphenation points for words in English (ayur-veda), and for words in Sanskrit (āyur-veda).
To use it, do something like this in your style file:
\setotherlanguage{sanskrit}and \input the sanskrit-hyphenations.tex file after \begin{document}, thus:
\newfontfamily\sanskritfont{Sanskrit 2003}
% Define \sansk{} which is the same as \emph{}, except
% that it causes appropriate hyphenation
% for Sanskrit words. Use \sansk{} for Sanskrit and
% \emph{} for English.
\newcommand{\sansk}[1]{\emph{\textsanskrit{#1}}}
\begin{document}
\input{sanskrit-hyphenations.tex}
...
\end{document}
XeTeX already has built-in hyphenation rules for Devanāgarī and Romanized Sanskrit. The above file is intended to extend the hyphenation coverage for Romanized words, using etymological and stylistic considerations.
