Karuna or compassion is a spontaneous flowering of love and awareness. When you live in oneness, you are the world, and you treat others as you would like to be treated - with kindness and respect.
Difficulties may arise with the practice of compassion by unconscious seekers; when compassion is unaware, the possibility of pretence increases.
This common spiritual trap can be avoided through the understanding that all your actions, words and thoughts come back to you. No other morality is needed.
Your self-interest is being served by helping others and in living with sensitivity and care. Self-interest prevents the spiritual ego from becoming holy and pretentious.
Osho taught awareness as the only morality. This is the way for those who are already aware. But while you still have negativity, please understand that by hurting other creatures you also hurt yourself. This insight into the law of karma provides the foundation for a new and healthy morality based on natural self-interest.
Before awakening, it helps if you can cultivate kindness without developing a holy spiritual ego. Those who meet life with an open heart enjoy the fruits of loving kindness.
After enlightenment, compassion continues its fragrant flowering as awareness grows, and your heart opens and opens in the miracle and wonder of cosmic love.
