@jwalanta Yes dai..I also found \usepackage{devanagari} really tedious.
This link ---
http://tex.loria.fr/fontes/devanagari.ps.gz ---- contains the character set to be typed in to get the corresponding devanagari character. But I felt its lack of flexibility.
I am still confused about how " े " will be displayed with {\dn e} .Similar confusion with " ा " .
Anyway, just as a reference I would like to note down the steps I carried out to get my task running.
1. Went to Synaptic Package Manager (OS is Lenny)
2. installed texlive-latex-base , texlive-lang-indic , texlive-fonts-recommended
3. In the text editor
a. included \usepackage{devanagari}
