Not always do you get what you can see.
The distance to the aim might cause some trouble.
Or what you see can something different be
and the illusion bursts like a soft bubble.
Illusions, though, can help to be inventive.
They propagate ideas to ease our ways,
and even without further keen incentive
as our phantasy comes free and often stays.
Without illusions our lives are dreary,
for even when they stay in our mind
as just a sentimental fiction theory
they trigger actions which can help mankind.
