The solution is not that I stop all action. Rather I stop acting for myself. Whenever I act in a self-centered manner, there will have to be some karmic reaction coming back to me. But I can act in harmony with my eternal spiritual nature and not act for myself anymore. The eternal spiritual beings by nature are happy when they can engage in loving service. This is our natural and healthy condition.
In fact, loving service is so purifying that it will actually burn off any karmic reactions that are still waiting there from the past and which one is still meant to experience in the future.
So, we can give up the world of karmic reactions, give up the world of repeated birth, disease, old age and death. We can get on to the platform of spiritual life, eternal life and eternal happiness, eternal loving service of the Supreme and others.
