The Eternal Law of the Pendulum

Lust can never bring happiness, real contentment. We have the idea that lust can bring happiness, and it can bring pleasant sensation, but we do not see that those sensations are a pendulum of energy. The more we push to have pleasant sensations, the more that pendulum swings back to painful ones. This is the eternal law of the pendulum.  Craving and aversion are the pendular movement of suffering.  We set that in motion continally, so long as we listen to desires.
