Contemplation: Salt Water

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

Indulging sense pleasures is like drinking salt water--however much one indulges, thirst and craving only increase. Immediately abandoning whatever things give rise to clinging and attachment is the Bodhisattva's practice.
