I See Only The Past.

This idea is particularly difficult to believe at first. Yet it is the rationale for all of the preceding ones.
It is the reason why nothing that you see means anything.
It is the reason why you have given everything you see
all the meaning that it has for you.
It is the reason why you do not understand anything you see.
It is the reason why your thoughts do not mean anything,
and why they are like the things you see.
It is the reason why you are never upset for the reason you think.
It is the reason why you are upset because you see
something that is not there...

Look about you. This is equally true of whatever you look at. Acknowledge this by applying the idea for today indiscriminately to whatever catches your eye. For example:

I see only the past in this pencil.
I see only the past in this shoe.
I see only the past in this hand.
I see only the past in that body.
I see only the past in that face.

Do not linger over any one thing in particular, but remember to omit nothing specifically. Glance briefly at each subject, and then move on to the next. Three or four practice periods, each to last a minute or so, will be enough.
