Because it is not seen does not mean that it does not exist. Love's effect in a home, Nation, or even in one person can be felt and seen even as the wind can be felt and seen. Love is more forceful than Light. Love will break down many more barriers than light Light can not penetrate walls or buildings, while Love can. There is no barrier for love except that a person does not want Love in his life and is rejecting love wilfully or unconsciously.
Every person needs love as one needs food and water.
Love and life go together hand in hand. If one chooses to live without love, he can do so, but not for long. The message is that love is powerful in its properties, its uses and its elements. Love is so powerful that using a even small amount of love, we can heal minds and relationships. The ability to send thoughts of love to another is very powerful.
