If true happiness and fulfillment derived from having possessions or money, then I know some people who aught to be the happiest. But With all the wealth and possessions they still live in lack and want for something more.
You ask how do I know that?
Why will a boss rape/molest his secretary,
why will a president have an affair,
why will a man or woman with a wife/ husband and children cheat,
why will they resort to pedophilia and rituals,
why will they spend all their money on counselors,psychiatrists,drugs etc
Giving is a sacrament that goes along way to curb our selfish ambitions and desires reminding us of the greater truth;the purpose of our existence.
So when next your mind or peers whisper and tell you you are over giving your time,talents,resources,etc for the good of others,that is the time to give even more! It brings satisfaction and joy that cannot be explained,you can only experience it!
A prosperous mind is a deposit of treasures yet unknown to men.
Invest in feeding your spirit and your mind and it will reflect in your hands and body.
Find joy within and let your light so shine that all may see!
