I had three more doubts
1) Are Puranas real stories or not or just symbolic and metaphorical as many say like Swami Chinmayananda (I am not a follower just quoting for the sake of asking) just to complement the Vedas. Do Puranas lead to sectarianism/radicalism and division within Hinduism
2) What do Sri Vaishnavas think of Sri Madhavacharya

3)Are all authentic Upanishads mentioned in Muktika Upanishad 108 Upanishads or can there be more authentic Upanishads like Purusa Bodhini Upanishad or any other Upanishad
