Ramayana
Disclaimer: I learnt this as a kid, from parents not totally conversant with Sanskrit. In other words, there's more of Shruti and Smriti in this than structural soundness.
Ado rAma tapOvanAdhigamanam etvA mRgam kAncanam
Vaidehi haraNam jaTAyu maraNam sugrIva sambhaSanam
vAlI nigrahaNam samudra taraNam lankApurI dAhanam
pashchat rAvaNa-kumbhakarNa hananam tretAdirAmAyaNam
Each line above had the following scheme (one swara for each syllable):
This is a version of the Ramayana that my brothers and I were taught as kids. Although encouraged to say this every night, I would usually fall asleep before I was half-way through it. But at those not-so-occasional times when the mind's eye saw faces in the dark, and heard whispers in the corners, and everyone but I seemed asleep and oblivious to my doom at the hands of the "vile contagion of the night", I clutched the end of my mom's saree and recited this devoutly. And the solace I found then still sweeps over me today.
