Swami Dayanand Saraswati Commentary : When the created world goes in the cause form, i.e. the Supreme Lord, creator of the world, who creates the universe from whatever material causes, creates many work objects (in the creation), and again converts and keeps these created objects in the cause form after properly maintaining them; is called ‘Holocaust = Dissolution of the Universe’.

महर्षि दयानन्द व्याख्या : जो कार्य जगत् का कारण रूप होना, अर्थात् जगत् का करने वाला ईश्वर जिन जिन कारणों से सृष्टि बनाता है, कि अनेक कार्यों को रच के यथावत् पालन करके, पुनः कारण रूप करके रखता है, उसका नाम 'प्रलय' है ।
