In plain words
By karma is a creature born, by karma it grows, and by karma it goes; karma is man's God, karma is the cause of joy and sorrow on this earth!
In the world many people go through hardship and happiness. When hardship comes, they think it is their karma. When happiness comes, they rejoice, saying it is their good fortune. But karma itself is the cause of both, hardship and happiness alike. “As the feeling, so it becomes.” Whatever food we eat, of that very food comes the belch. In the same way, as are the actions we do, so is the very result we go through. This whole world runs by karma alone. So the karma we perform must be sacred.
Now we are celebrating the Dasara festival. What is its inner meaning? We celebrate this Dasara festival precisely to sanctify the actions we perform with the ten senses. In this world every human being must perform actions. For this, first of all, we must win the Devī's grace. She is the very form of power; by her power she keeps every action in the world going. That is why, when the Navarātri come, we worship the Devī. Through that worship of the Devī, energy enters us. Through it Lakṣmī grants us wealth and grain, goods and vehicles and the like; and Sarasvatī bestows learning and intelligence. Is it not only when there is power that wealth and grain, goods and vehicles, learning and intelligence come within our reach? That is why these Navarātri have kept teaching us that it is most necessary to worship these three, Durgā, Lakṣmī and Sarasvatī. In these Navarātri, when we set our ten senses on the path of Dharma, we gain nine kinds of powers.
