A single negative element can negatively impact and contaminate an otherwise positive whole. The document provides numerous examples to illustrate this point, such as how a single rotten apple can spoil other good apples, a single stain can ruin an otherwise clean fabric, and a single lie told can condemn an honest person's reputation. Ultimately, it suggests that a single devilish thought in the mind can ruin one's mental, physical, and spiritual well-being.

1. A SINGLE DEVIL
A single rotten apple with flies feasting on its succulent body; decays the entire
ensemble of robust apples,
A single stain of black dye sprawling rampantly; spoils the beauty of the entire white
fabric,
A single hole in its heavy and metallic body; uncouthly drowns the entire ship,
A single stream of venom oozing gently; contaminates the entire river of impeccable
milk,
A single bit of sewage smelling fetidly; annihilates the beauty of the entire garden
laden with blossoming petals,
A single virus in the blood stream; metamorphoses the individual from rubicund and
healthy to insane and sick,
A single particle of dandruff loitering in animosity; pollutes the entire conglomerate
of lustrous and shining hair,
A single nail overgrown and dirty; imperils the look of the entire palm embossed with
mystical lines,
A single dark cloud in the cosmos; adulterates the entire sky which is blue and
crystal clear,
A single town clock running late; delays the life of the entire city; with most of the
people yawning as the sun crept up in brilliant afternoon,
A single loophole in the house; entices the entire team of burglars to maraud at will;
pilfer stealthily through closed doors at night,
A single crack in the bone; foments the entire leg to walk in contorted pain; limp
across the road for mercy,
A single spark of white electricity; electrocutes the entire family; triggering the house
to explode in volatile fury,
A single crease in the crisp shirt; debases the entire demeanor which was otherwise
quite sparkling and flawless,
A single snore thunderously emanating; breaks the silence of tranquil and

2. blissful sleep,
A single shiver down the petrified spine; engenders the snake to pierce its lethal fangs
and bite,
A single stroke of stringent red; disturbs the harmony of the otherwise splendid
marksheet,
A single lie spoken; condemns a person beyond all anecdotes of his honesty,
And a single devil in the mind; not only ruins all the sanctity previously existing; but
also finishes a person in mind, body and eternal soul.
