Jayapataka Swami: Srila Prabhupada stressed the importance of attending Mangala Arati. We got 24 hours to finish the 16 rounds, and I don’t know why it takes 40 minutes for Mangala Arati, usually it only takes only 20 minutes. Making the offering first and doing all the ceremonies that may take some more time, but the actual arati does not take that much time. Mangala Arati is supposed to be more fast. The noon arati is longer, evening arati is longer, but the Mangala Arati is supposed to be short. So ideally, you should try to do both.
