The opposing reaction of basically the same function, or the same expression just placed in a different direction, is anxiety. Anxiety is the desire, or conscious energy moving into the future... so in the cases of guys running a cycle of orals, while dreaming about future cycles and not paying attention to the cycle they are in, will create a sense of anxiety. The anxiety is created out of this tension of the present moment, and the desire to do something different in the future which you are not doing in the present; or basically put the desire to be what you are not in the present; the tension between that what you are (whatever it is you are doing and the state that you are in, in this present moment) and the desire to become something different than what you already are (so, the desire to run a different oral cycle for example, somewhere in the future, that you are not currently running) creates a split; this split is between being, and becoming. What you are, and what you want to be... this split creates anxiety.

As someone who has had a lot of anxiety in their life, I can vouch for this. The knowledge that anxiety is created from not accepting the present has been very liberating for me. But I still have a lot to learn.

Don't we all?
