Determination and Impermanence
The mind &amp; all mental things are impermanent. When the body ends its life, the mind also is impermanent. 

But during life, for a Fully Enlightened One, the virtues of the mind are permanent. 

The Buddha said of himself: 


  I am now old, aged, burdened with years, advanced in life, and come to
  the last stage: my years have turned eighty... Sariputta, even if you
  have to carry me about on a bed, still there will be no change in
  the lucidity of the Tathagata's wisdom.
