What is the opposite of Love?
It is not hate.
It is indifference.
The simple truth is out there. If you love some one, some thing or some ideology, you have to give a damn. Hate is the other side of the same coin.
What is opposite of happy? It is not sad.
It is bored.
The thing is, most of the things out there are simple and pretty obvious. But we do not want to observe, only complicate. We want to complicate.
If you want to find happiness, find things that interest you.
Be interested in life, and you will AUTOMATICALLY find God, find peace, find happiness.
