Observe yourself when you love someone: the mere presence of this feeling inside you makes you think and behave in a certain way, and not just towards the person you love.
Because of this feeling, your relationships with everyone around you and even with nature are different.
Love is a force that acts on you, on your mind, on your will and even on your body; it gives you immense possibilities. Love is like fuel: if there is fuel in your car, you can drive.
But if you lack fuel, where can you go?
