Phases are like breathing

When someone tells me is going through a bad phase I tell him it's just a phase that will have an end.
The notion of ephemerality and transience reliefs and allows us to learn.
When somenone asks how can we be sure that these phases will have an end , the answer is - breathing.
It is like inspiration and expiration.
Listening to the sounds.
Noticing our thoughts.
Nothing is fixed.
Nothing is permanent.
