From lifelessness came life; from dead matter came spirit.
With life came perception: the perception of beauty and ugliness, serenity and fear.
The Force grew strong as life grew stronger.
Life is the universe's way of perceiving itself; the Force is the strength of its perception.

Perception: Perception is the power that controls one's reactions to events that are happening at the very moment.
