Compassion is the fragrance of the Spirit. When we are spiritually connected then compassion flows even for them who are never forgiven by others. Compassion evokes the light of forgiveness that is purely the flame of the Spiit within.
It is only when we allow the Divine to flow through us that those feelings of compassion and forgiveness fill us.
We can't be compassionate. That is false. We can only be open to the eternal Light that guides us from within at all times. Then God flows through us. Compassion is the quality of Godliness in us, a divine quality that can manifest when the ego is sublimated to Higher Light.
In a humbled state of mind, compassion flows as a divine gift, there cannot be a greater gift to the world for peace and blessedness.
