"The truth is, we all carry our prisons within us."
A mind conscious of its purity is attached to nothing， neither to the body nor to the soul.

"The truth is rarely pure and never simple."
To feel much for others and little for ourselves； to restrain our selfishness and exercise our benevolent affections， constitute the perfection of human nature.
