My pick of the litter:
24: Give Up Labels
“In the sky, there is no distinction of east and west; people create distinctions out of their own minds and then believe them to be true.”
I think this can relate even to the concepts of government and laws.
These are imaginary barriers of words written on paper and then brought to life only through the power of our own mind to imprison ourselves.
If you want to change your reality, you merely need to think about it differently.
