A moving of the mind or soul; excitement of the feelings, whether pleasing or painful; disturbance or agitation of mind caused by a specific exciting cause and manifested by some sensible effect on the body.
Unconditional love really exists in each of us. It is part of our deep inner being. It is not so much an active emotion as a state of being. It's not 'I love you' for this or that reason, not 'I love you if you love me.' It's love for no reason, love without an object. Ram Dass
The oldest and strongest emotion of mankind is fear, and the oldest and strongest kind of fear is fear of the unknown. H. P. Lovecraft
