From Contemplation of Feeling: The Discourse-grouping on the Feelings (WH 303), translated from the Pali by Nyanaponika Thera (Kandy: Buddhist Publication Society, 1983). Copyright ©1983 Buddhist Publication Society. Used with permission.

Just as in the sky above winds of various kinds are blowing:
Coming from the east or west, blowing from the north or south,
Some carry dust and others not, cold are some and others hot,
Some are fierce and others mild -- their blowing is so different.

So also in this body here, feelings of different kind arise:
The pleasant feelings and the painful and the neutral ones.

But if a monk is ardent and does not neglect
To practice mindfulness and comprehension clear,
The nature of all feelings will he understand,
And having penetrated them, he will be taint-free in this very life.
Mature in knowledge, firm in Dhamma's ways,
When once his life-span ends, his body breaks,
All measure and concept he has transcended.
