You already know, intellectually, that when someone says something hurtful or acts in a mean way, that they themselves are feeling fearful or hurt or utterly confused.
But to look past those behaviors calmly, and to not let the hurtful words or actions touch and hurt you, you must truly feel the Deep Compassion that x-rays through the human condition. Look, and understand, with that Compassion, and see the Soul of the person, that is Divine, and is the same Infinite Soul all share. Feel the same Soul rise up in your Consciousness, and allow It to help you respond with Love, and guide you to the silence, or words, or actions that are the Perfectly Holy response.
Be a healer of the human condition by bringing in Love,
