The old sages didn't tell us what "is" but only that it is "not this" and "not that".
The true holding on is letting go, not embracing.
True form is formless, "being" encompasses so many things that it cannot be differentiated.
True courage is diving head on into fear, not keeping your fear at bay.
True strength is gained by exposing weakness to discipline, not indulging in weakness.
True peace is maintained in discord.
True experience is seen and felt, false knowledge is produced by thought...
...yet everything is created by the mind.
True waste is always recycled anew, true produce is always bountiful when one knows how to obtain it.
True light carved out of darkness.
True life given by the spirit, which is the breath.
True life is lived, true death is dead.
True void is substance,
True substance is insubstantial.
One's disastrous situation is good fortune for another's life,
Nothing is the same for anybody.
Existence is measured on scale.
There is no reason to get rid of the scale as the end of the scale means the end of you.
...and there is nothing there to end.
