Why do we habitually use mind-altering substances and strategies in ways that are not always healthy? Here's a very simple explanation which holds in some way (I believe) for all of us.

THE DOOR

Go and open the door.
Maybe outside there’s
a tree, or a wood,
a garden,
or a magic city.

Go and open the door.
Maybe a dog’s rummaging.
Maybe you’ll see a face,
or an eye,
or the picture
of a picture.

Go and open the door.
If there’s a fog
it will clear.

Go and open the door.
Even if there’s only
the darkness ticking,
even if there’s only
the hollow wind,
even if
nothing
is there,
go and open the door.

At least
there’ll be
a draught.
