The human body at peace with itself
Is more precious than the rarest gem.
Cherish your body.
It is yours this time only.
The human form is won with difficulty.
It is easy to lose.
All worldly things are brief,
Like a flash of lightning in the sky.
This life you must know as the tiny splash of a raindrop
That disappears even as it comes into being.
Therefore set your goal.
Make use of every day and night to achieve it
Je Tsongkhapa, 1357–1419, Tibetan Buddhist monk
