One means a lot

A sharp sound,
all the birds flew away.
A small spark,
fires the entire forest.
A single asteroid,
destroys the entire world.

A minute glance ,
fills thy mind.
A silent word,
means a lot.
A gentle touch,
vanish the pain.

One book,
takes you to many world.
The sun,
lightens the entire earth.
The moon,
only natural satellite.

Everything begins and ends
when i shut and open my eyes.
