Contemplation: Briefly Lent to Me

After reviewing the guidelines for practice, take the following as your object of contemplation:

The appearance of the buddhas in the world,
True faith and the attainment of the human form,
An aptitude for good:  all these are rare.
And when will all this come to me again?

Today, indeed, I'm hale and hearty,
Have enough to eat, and am without affliction.
And yet this life is fleeting and deceptive.
This body is but briefly lent to me.

Santideva, The Way of the Bodhisattva, p. 56
