Although we are all the same in not wanting problems and wanting a peaceful life, we tend to create a lot of problems for ourselves. Encountering those problems, anger develops and overwhelms our mind, which leads to violence. A good way to counter this and to work for a more peaceful world is to develop concern for others. Then our anger, jealousy and other destructive emotions will naturally weaken and diminish.
Jealousy is comparison. And we have been taught to compare, we have been conditioned to compare, always compare. Somebody else has a better house, somebody else has a more beautiful body, somebody else has more money, somebody else has a more charismatic personality. Compare, go on comparing yourself with everybody else you pass by, and great jealousy will be the outcome; it is the by-product of the conditioning for comparison.
Love makes you empty - empty of jealousy, empty of power trips, empty of anger, empty of competitiveness, empty of your ego and all its garbage. But love also makes you full of things which are unknown to you right now; it makes you full of fragrance, full of light, full of joy.
An affectionate disposition not only makes the mind more peaceful
and calm, but it affects our body in a positive way too. On the
other hand, hatred, jealousy and fear upset our peace of mind, make
us agitated and affect our body adversely. Even our body needs peace
of mind and is not suited to agitation. This shows that an
appreciation for peace of mind is in our blood.
