David's commentary continuted: "And so, today's lesson is the first, the first attempt here in the workbook, where Jesus is joining with us and saying, 'I want to convince you, I want to convince your sleeping mind that thoughts that you think you think all through the day are not really what you think, because they're not real, because they don't have any MEANING'. Children who are asleep play with false concepts of the Self, false thoughts, false images, and it's no wonder Christ is beckoning to us, calling to us, through every upset, through every perception of pain, or fear, guilt, shame, doubt.  Christ is calling to us, saying, 'THIS NEED NOT BE': lay aside these toys of unreal thoughts and come within, come WITHIN to find meaning, come WITHIN to find purpose, come within to find your true identity as the living Christ - not a man, not a woman, not a human being, not a character with a role to play: 'THESE THOUGHTS DO NOT MEAN ANYTHING'.  And as we look around in our mind, we see that there seems to be only one station playing, initially, and that's the past-future channel.  If our thoughts were a radio station that was broadcasting, they could call the radio station past-future.  That's the broadcast going on every second, every minute, every hour, every day, every week, every month, every year, every decade, every century; and: THESE THOUGHTS DO NOT MEAN ANYTHING. Some of you are familiar with Zen Buddhism, 'form is empty, empty is form': and WHY is form empty, except: THESE THOUGHTS OF FORM, THESE THOUGHTS OF PAST, THESE THOUGHTS OF FUTURE, DO NOT MEAN ANYTHING.  Now we can relax as we give our mind over to this beautiful thought for the day: 'These thoughts do not mean anything'.  And we can trust that we are being gently worked with, that the realization that this lesson points to is ABSOLUTELY profound; and yet nothing is taken away, it's just a call to realize, to recognize what has no meaning.  And the ego may tempt the mind during the day to put some meaning back on the thoughts, as if there's a reason for these thoughts, as if there's a value for these thoughts, as if some of these thoughts can help you, protect you, as if these thoughts that cross the mind all day, these fleeting thoughts, as if these thoughts can be YOU, which is the farthest thing from the truth, the very, very farthest thing from the truth.  So we now make the attempt to stop and watch and sink within toward: 'be still, and know that I am God'; toward the Truth of our Being, away from the temporary, the ephemeral, the fleeting, and inward toward certainty.  Practice with focus on this idea for today: 'These thoughts do not mean anything'."
