The brief elation we experience appeasing sensual impulses is very close to what the drug addict feels when indulging his or her habit. Temporary relief is soon followed by a craving for more. And in just the same way that taking drugs in the end only causes trouble, so too does much of what we undertake to fulfill our immediate sensory desires. We must acknowledge that there can be no hope of gratifying the senses permanently. At best, the happiness we derive from eating a good meal can only last until the next time we are hungry.
