Mythology means that they are just stories, that never happened in the real world. These stories are made to teach people about different things. The end of all collections is destruction, the end of worldly progress is fall, the end of the connection is subtraction, the end of life is death. Happiness from the subtraction, how to get it, not to have happiness and sorrow, to come and go. The one who is connected is also subtracted, enjoying the connection is the same thing, be satisfied when you get respect, get insulted only pain. Then Byasadeva thought, those who will be engaged in Yajna, reading, those who are meritorious, devoted - they will be liberated by the meaning of the Vedas. What will happen to those who are less gifted or do not have time to read Vedas or are not fit to acquire meaningless knowledge? With this in mind, Byasadeva composed the Mahabharata and Puranas through stories, exhortations, stories, etc., theories of the Vedas, so that the less intelligent human beings, by realizing the Mahabharata, Puranokta theory, can transcend the illusion and attain liberation/devotion. He composed the Brahmasutra with the incarnation of argument. Byasadeva's purpose in composing all these books was - cessation of the subject, attachment to God, and liberation. In the Manusanghita Arthashastradi, the Puranas are revered and placed in harmony with the Vedas. The importance of Puranas has not diminished even in modern times.
