Satisfactions - do not seek them on the physical plane

Without always being aware of it, human beings tend to seek most of their satisfactions on the material plane, which renders them egotistical, unjust, dishonest and even criminal. For an increase in salary, a higher position, a greater share in the market, or a social invitation, they embark on intrigues and agree to all kinds of compromises. Even if they attain their ends, what do these successes actually bring them? So many of them, once their desires are fulfilled, feel even more dissatisfied! They have wronged others, and not only are they themselves no happier, but in their heart and soul they have lost elements which are infinitely precious. Is this really worthwhile?
