Contemplation: The Sunlight of a Cloudless Sky

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

Why does the mind, intent on filthiness,
Neglect the fresh young lotus blossom,
Opened in the sunlight of a cloudless sky,
To take joy rather in a sack of dirt?

Santideva, The Way of the Bodhisattva, p. 118
