Love is compassion and kindness. Love is a state of consciousness, not a passing emotion. Love expresses itself in many ways, and defines itself by our actions and vibrational essence. We can reshape the world, one kind gesture at a time.
You do not have to be a Buddhist or a Hindu to understand karma in a modern context and put it into action to create positive outcomes in your life. It means that whatever we project out into the world is recycled back to us. It also can be defined as vibration. Thoughts, emotions and mental energy are all vibration, and any resonance or frequency attracts to itself more of the same.
