"Frustration and discontent due to one’s failure to resolve life’s problems, separation form one’s associates and friends, unfulfilled hopes and desires, are other forms of oppressions inflicted by feeling. Even pleasant feelings, which are very comforting by giving happiness while they last, prove to be a source of distress later. When they disappear after their brief manifestation, one is left with a wistful memory and yearning for them. One has, therefore, to be constantly striving to maintain the pleasant happy state. Thus people go in pursuit of pleasant states even at the risk of their lives."

Further he writes "Feeling is ungovernable and not amenable to one’s will". It takes some contemplation to realise that as feelings (physical and mental phenomena) are therefore not-self. They can be known, but their arising is ungovernable.

The 'path' : "In the initial stages of meditation the meditator suffers from physical discomfort: stiffness, itching, or feeling hot. Occasionally, he or she also suffers mental distress such as disappointment, dejection, fear, or repugnance. One should keep on noting these unpleasant feelings. One will come to know that while these unpleasant feelings are manifesting, pleasant sensations do not arise. On some occasions, however, the meditator experiences in the course of meditation very pleasant physical and mental sensations. For instance, when one thinks of happy incidents, feelings are involved. One should keep on noting these pleasant feelings as they arise. One will come to know then that while pleasant feelings are manifesting, unpleasant feelings do not arise. On the whole, however, the meditator is mostly engaged in noting the origination and dissolution of ordinary physical and mental processes such as the rise and fall of the abdomen, which excite neither painful nor pleasant sensations. The meditator notes these occasions when only neutral feeling is evident. He or she knows therefore, that when the equanimous feeling arises, both painful and pleasant feelings are absent. With this personal knowledge, comes the realisation that feeling is that which makes a momentary appearance, only to vanish soon; hence it is transitory, and is not a self or ego to be regarded as permanent."

Essentially this leads to noting the continual, ungovernable flux that is reality and thus noting not-self (it is ungovernable and therefore not-self) and that misery comes from clinging to this continual (not-self) change.
