We are not always rewarded for the good we do, but that must never be a reason to regret having done it. Let us say you have given someone material support, and then one day, you discover that they did not deserve your help. Not only were they ungrateful, ...
Let the spring of love flow within you. Through your thoughts, your feelings, your wishes, your words, let it gush forth over all the creatures and objects around you and beyond, on the trees, the mountains, the oceans. Even if you are by yourself, remember to utter words of peace, of hope and of joy for all human beings on earth, knowing that these words will have an effect somewhere, no matter where. You do not yet know what it is possible to achieve with love.
And since we can only give to others what we possess ourselves, try first to establish harmony and light within you, and then, once you feel you have succeeded in making this harmony and light real within you, in your heart and your soul, project them into space. This is what working with love is all about: becoming a beneficial presence for the entire world.
