Applications – None can Challenge

Light and dark,
the one shines,
spreads life,
acts and reacts
with aplomb

The other quells,
stands solitaire,
remains quiet,
dispels and diffuses
with serenity.

A clash of clan one sees
where egoism outsmarts,
the one overlaps
while the other succumbs
a play in the cards.

These are applications
not man made, go back
to time immemorial,
are loaded with techniques
intricate and fine.

Both work with a time table,
light has the day
for its activities
the dark confines
to the whole night.

A software programmed
long time ago ,
stays tall with none
to challenge. Tech giants
will never find one similar.
