We start out as parcels of awareness that can use our creative energy to create imaginary thought Worlds. If we create something unpleasant, then we'll have to live according to it.
Last night I had a meditation. My mind was creating unpleasant sensations. I saw more than ever that regardless of how our minds make use of our creative thought energy, no matter how we make this creative energy appear, in truth it is still divine creative energy that never completely takes on the form of that which we create.
Certainly the awareness aspect of our being never gets touched. We can cause it to experience different things, but it can never be touched.
Love is beyond being altered. We can cut ourselves off from experiencing it, but we can never alter it.
There is also the viewpoint that thought energy doesn't just come and go. If you create a negative thought, you'll end up sharing it with at least a part of the rest of the universe. But don't hit yourself over the head if you have a negative thought. If your mind is going to have the ability to function properly, then it has to have the ability to consider all possibilities, even if some of those possibilities are unpleasant. In the end what it comes down to is what we're emotionally attached to and what we believe. For example, it doesn't hurt one to believe that this planet is going to be invaded by a planet of pink frogs, if one doesn't believe that this is true. Just don't share the theory with somebody else, because somebody is liable to market it.
