If you think it so it is and this is because the thought arises from the same energy that the action would be and this energy being based in self centeredness makes the thought and action one in the same.
There’s a verse in the bible that says something like “If you think it so it is” This isn’t an issue when the first thought comes in because there’s not much one can do about that, but it does become an issue when the thought is given energy for it to come alive and this is even if the thought is never acted on. This occurs because of one’s self centeredness and this is why it’s an issue, it blocks one from their own innate love. Here’s an example: It’s not wrong to look at a woman, or to find her attractive. It’s not wrong to think of a man as handsome, but if a married man or woman goes farther and starts fantasizing about kissing or having sex with someone other than his or her spouse, then he or she has taken the thought to the level where it now becomes one’s bondage and blocks out the love of from one’s own heart. This is when an issue would arise.
This issue doesn’t occur when the thought, emotion, or passion arises, but if those thoughts aren’t resisted then issue occurs because we give in to the emotion, thought, or passion by dwelling on it, and this is only the thought, not an action. If the action of the thought is acted on, the bondage goes to an entirely different level with much more dire consequences. But it all starts with a single thought and if the thought isn’t given energy, an action cannot occur. This is true with any thought, whether it’s anger, lust, greed, and so on, if there isn’t bondage to the self centered base, there wouldn’t be further attachment to the incoming thought and if you don’t think it, it cannot be so.
