And there are innumerable universe. They are clustered together. And all these universes together is called the material world. And this is a very fortified place, and the predominating deity of this material world... Sṛṣṭi-sthiti-pralaya-sādhana-śaktir ekā (Bs. 5.44). There is a power. That is called Durgā. Sṛṣṭi-sthiti-pralaya-sādhana-śaktir ekā chāyeva yasya bhuvanāni bibharti durgā, icchānurūpam api yasya ca ceṣṭate sā (Bs. 5.44). Although this Durgā is so powerful that she can create, she can maintain and she can dissolve, the whole cosmic manifestation... It is so powerful. At any moment it can dissolute.
But she is working just like chāyeva. Chāya means shadow. Just like you have your hand and here is the shadow. If the hand moves, then shadow moves. Therefore it is said chāyeva yasya bhuvanāni bibharti durgā. (end)
