In 1906, an earthquake ruptures the San
Andreas Fault devastating 3,000 people.
If vibrations can break boulders and devastate
lives,
Then our words can split open minds and alter
the geographical shape of its content,
because sound is vibration
Our verbs are its earthquakes, and our hands
are much like the Richter scale
Charting the magnitude of our words, so when
you write
Fight the urge to destroy your enemies because
an earthquake
Named Gandhi
Once told me even revenge has aftershocks
That even a whisper can cause a revolution
In 2010, an earthquake takes the lives of
300,000 Haitians
Dor underestimate the Hercules behind your
tongue
Your voices are the reason this planet's axis is
tilted, but your silence is the reason this
planet is dying
