Dhammapada 7-8 [Khuddaka Nikaya]

I- Yamakavagga, The Pairs
6- Mahakalatthera Vatthu 

Subhanupassim viharantam,
indriyesu asamvutam;
bhojanamhi camattannum,
kusitam hinaviriyam;
tam ve pasahati Maro,
vato rukkhamva dubbalam.
 

Asubhanupassim viharantam,
indriyesu susamvutam;
bhojanamhi ca mattannum,
saddham araddhaviriyam;
tam ve nappasahati Maro,
vato selamva pabbatam.

He who keeps his mind on pleasant objects, who is uncontrolled in his senses, immoderate in his food, and is lazy and lacking in energy, will certainly be overwhelmed by Mara, just as stormy winds uproot a weak tree.

He who keeps his mind on the impurities (of the body), who is well-controlled in his senses and is full of faith and energy, will certainly be not overwhelmed by Mara, just as stormy winds cannot shake a mountain of rock.
