Similarly, monks, there arise in this body various kinds of feelings: pleasant feelings arise, painful feelings arise and neutral feelings arise.
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."
~ The Buddha
