Jealousy is a human trait.  There is no envy amongst those who know that all contribute to the whole.  If another seems to have more happiness than you, or perhaps more toys, send them love.  That which you send out comes back to you.  Suddenly, you have happiness, and the desire for toys and self-importance goes away.   
 
In sending love, you have activated the very Force which gives you life.  Your spirit grows and expands, and you understand that all are here to learn to love.  With such an understanding, there is no envy, only rejoicing that you are all in this together.  Envy disappears as you understand that you all need all the help you can get in helping others to see the Light.
