“The human body, at peace with itself, is more precious than the rarest gem. Cherish your body, it is yours this one time only. The human form is won with great difficulty, it is easy to lose. All worldly things are brief, like lightening in the sky; this Life you must know as the tiny splash of a raindrop; a thing of beauty that disappears even as it comes into being. Therefore set your goal, make use of every day and night to achieve it.”
– Tsongkhapa.
