Wise people know that attachment is the source of suffering.

When we are attached to something,
we suffer from feeling bad when we lose it.
Outer events can manipulate the inner feelings of people who are attached to certain things.

Some people who choose to dwell in past memories are said to be attaching to past events. They just choose not to let go…..

Realise that events, pasts and everything that exist around us are just illusion.
When we extent the time frame to infinity,
there will be no event that really matters, as events are just temporary.

For example,
if you feel sad when you lose 50 dollars.
such an event is insignificant after 30 years, 60 years, a lifetime, millennia.
It has a beginning, and it will reach its end.

So realise that events are illusions that exist temporary
and choose not to adhere to them.
Choose to let go and be free.
