When opposing desires are present, they generate opposing energetic currents, with the current from the negative desire holding back the realization of the positive one.
It may be difficult to identify the negative desire and its forcing current because there usually is a (negative) pleasure attached to it. This pleasure may disguise the negative desire as just one more positive, non-conflicting desire.
Think of a conscious, positive desire that you have and that has not been fulfilled so far. Think of any possible contrary desires that you may have and the reasons for their occurrence. What possible pleasure might be attached to the desire of not realizing the positive desire?
The following example will clarify the exercise:
Suppose that a person has a chronic illness that causes discomfort and pain; this person consciously has a positive desire of healing from that illness. Through honest self-confrontation, however, this person might realize that he also has a simultaneous, negative desire of not healing. The negative pleasure attached to the negative desire could be a feeling of safety and comfort because he believes that people will be more tolerant and compassionate toward him and not put too high expectations and demands on him because, after all, he has a handicap, he is a sick person.
These two opposing desires would cause pain and prevent the realization of the conscious desire. This situation would prevail until the opposing desires and pleasures are identified, brought to the conscious level and the conflict is dissolved.
When you understand the process of how opposing desires and pleasure interact, you will probably experience positive pleasure from this knowledge and its liberating power. But you may also see how this process is still affecting people with whom you interact. You might then develop a negative pleasure in observing other people’s faults, while feeling superior for being able yo observe that process from a vantage point.
