Rumi

This being human is a guest house.
Every morning a new arrival.

A joy, a depression, a meanness,
some momentary awareness comes
as an unexpected visitor.

Welcome and entertain them all!

(Unknown translator)

Every day is a day that comes from a finite number given to each life form and then it ends. Each morning it arrives in a unique and different guise. It won't come again. If we are lucky, we can remember the days. Some of us have certain medical conditions and we can't remember. Some of us don't want to remember for they have days that are too painful to recall. A man or a woman who survives the German Nazi Concentration Camps would not want to see their days there in memories although they would come back unbidden in nightmares.

Children who were severely abused often grow up to be adults who develop amnesia so they can forget the abuse. Many of the adults molested and abused as children often imagine themselves as survivors of German Concentration Camps. It is a way of surviving the horrible memories. Even the good days that come in the morning light of freedom cannot block those memories and many survivors cannot continue years after their abuse.

Each day comes floods of echoes of past memories and new ones often bring the old ones tagging behind. That is why some of us visit therapists for help in understanding that, if we are lucky. Old soldiers wake up in sweat soaked beds trying to forget the glory and the tears of battlefields.
Even the short lived butterfly has memories if not the caterpillar days, the lives before. No one knows who will walk through the door for there is no lock and no key. All will enter eventually.

It is best to offer your visitors some tea or coffee and a comfortable chair no matter who or why they come. It is also best to listen to them and what they have to say. Breath in and breath out the pain, sorrow and joy. They will keep coming until you do anyhow.
