Power of the mind

Yes, the power of your brain
or rather mind
is really great
I belive in those ESP rumours and mental power
It is the triumph of the willed
those who belive and hold strong faith will get what they want
Either they work for it, or they hope for it
The human brain is the greatest thing ever created
It is unique and powerful
who knows what lies inside, or what is happening inside
The whole secret of the universe may even be inside
but what we need now, is the key to unlock it
while it is hidden deep down inside our brain
So all these while we are trying to learn or 'absorb'
It would be better if it is referred to unlocked.
