Bhikkhus, I do not perceive any single fetter other than the fetter of craving by which beings are so tied and for so long a time run on and wander in samsara. It is indeed through the fetter of craving that beings are tied and for a long time run on and wander in samsara."
A man companioned by craving
Wanders on this long journey;
He cannot go beyond samsara
In this state of being or another.
Having understood the danger thus -
That craving is the origin of suffering -
A bhikkhu should wander mindfully,
Free from craving, without grasping.
