Mahārishi Parāśara said to Maitreya — O Brahmin! Now I will impart to you the knowledge of a great secrecy and superior importance which was communicated to me by Lord Brahmā himself for the benefit of the world. This is a chakra by the name of Sudarśana through which Daivajñas will be able to predict the favourable and unfavourable results for every year, every month and every day from the time of birth to the time of death of a person. Listen to this very intently.
