Understand?

I'm the lion and the tamer
I'm the tiger and the cage
I'm the circus and the freak show
Business acumen and rage

I'm the door and I'm the porter
I'm the time and I'm the age
I'm the book and I'm the scholar
I'm the pen and I'm the page

I
Am
A self con tained e co sys tem and
If
You
In tro duce a new spe cies it will
Up
Set
The ba lance of my bi o rhy thms
(tick... tock... tick... tock...)

I'm the patient and the doctor
I'm the master and the slave
Both the mother and the infant
Both the digger and the grave

I'm the moth and I'm the candle
I'm the light and I'm the cave
Both my love and my beloved
I'm both particle and wave

I
Am
A self con tained e co sys tem and
If
You
In tro duce a new spe cies it will
Up
Set
The ba lance of my bi o rhy thms
(tick... tock... tick... tock...)

I'm the lover and the warrior
The dreamer and the dream
I'm the paint and I'm the painter
I'm the nightmare and the scream

I'm bewitched and the bewitcher
I'm the plotter and the scheme
I invented the inventor
I'm the cat who got the cream

I
Am
A self con tained e co sys tem and
If
You
In tro duce a new spe cies it will
Up
Set
The ba lance of my bi o rhy thms
(tick... tock... tick... tock...)

I'm the gift and I'm the burden
I'm the hunger and the meal
I'm the hard truth and the questions
I'm the answers that conceal

I'm the words that cloud your meaning
I'm the kiss you never steal
I'm the life and I'm the heartbeat
I'm the fantasy of 'real'

I
Am
A self con tained e co sys tem and
If
You
In tro duce a new spe cies it will
Up
Set
The ba lance of my bi o rhy thms
(tick... tock... tick... tock...)
