Paired opposites define your longings and those longings imprison you.
- The Zensunni Whip

"Paired opposites define your longings..."
This world is based on relativity, things exist only in relation to each other.
So do you (there is 'you', and there is 'not you').
In this case I would define longing as a non-physical need to try to get and own something that is not you.

"...those longings imprison you."
Owning other things is an illusion. You cannot have what you long for because the need itself is the obstacle for fulfilling that need. You don't get things by wanting and needing, because the very act of longing for them places them beyond your reach!

If you want something then it means you don't have it (and that's the reason for wanting it).

Wanting realizes wanting and not having.

The more you want it, the more you don't have it.
It seems like a paradox, but it is not: The answer is to stop wanting it and have it.

 
And the world lies beneath your feet.

 
As said Yoda from Star Wars:
"Try? There is no try. There is only do or not do."

Replace "try" with "want" or "need" and this sentence will still be true.

Needs imprison you. They say "You must have this, you must do this. You can't have this and you can't do that". It limits you choices, it limits your freedom, it makes you "less" than you are.

Needs are fear of things that may happen if we don't fulfill our needs. Release your fears, be afraid of nothing, and don't let duality leave you torn apart.

Act out of choice and not need!

 
The Zensunni Whip is a whip because if you let it, it whips you out of this universe into a magical one where anything can happen: beyond words, beyond normal thinking, beyond your definition of yourself.
