The greatest wealth in life is one's own body and mind.
An excellent life can be summed up in three words: "pass", "light" and "new".
"Tong" means that the body and mind are very smooth, and the human life force flows in the body without any obstruction and entanglement.
"Light" means that the body and mind are very light, without any superfluous, useless, residual parts.
"New" means that the body and mind are renewing themselves every moment.
