I don't set that instruction aside, I'm waiting for you to explain what it does, how to do it, and when god comes into it...
What it does is restore your mind to its original pure state as if you were born again as a fully developed adult with the benefit of the lessons learned in life which transforms you into a new creature with miraculous almost godlike abilities to see things as they are, reject what is wrong and do what is right.
You cleanse your mind by sorting through everything lurking in the thought patterns and memories of your mind, all of the disturbing thoughts and memories hurt feelings and unsubstantiated assumptions that cause you discomfit or pain then cut it out and throw it away, little by little, one by one, day by day.
It could be anything. Life's a bitch and then you die, everybody is beautiful, there is no proof of God, what about the kangaroos. You know what I mean. These stupid thoughts feelings and sayings are what confuse you, your confusion is the barrier between you and your God. free your mind from the contaminating effects of your own perversions.
After you have finished you will see things that you never saw before and hear things unheard since the foundation of the world..
Still an additional effort is required after all that work is done to see God even from a distance or close enough to stand in his presence and hear his words.
