Let's try an experiment. Take an object, any object, in your house. Touch it with love everyday. While going out of the house, touch it gently and say Bye. When you enter, touch it again and say, "I'm home".
Within 2 months, you will find that the object radiates love. You will feel happier when u stand near that object. And so will the people who come to your house. Without any reason, that will become the favourite "spot" of everyone in the house.
What is happening here, is simply this - Love, as an energy, is unbeatable. Like a sponge, the object absorbs love. And then, it starts to radiate love back. It doesn't matter whether the object is animate or inanimate. It doesn't matter if its a pet or an idol. Or even a rock pet. This WILL happen. The target object is completely immaterial.
Now, imagine if you were doing this to people sharing the house with you. Or a child. Or a colleague. A friend.
