Adhi shankaracharya said: We are the Brahman.Jeevatma and paramatma are one and the same And this world is maya(which is surely not). He said that Brahman is impersonal and without any attributes and passtimes.

Ramanujacharya said: Brahman is both with and without attributes.He can have pass times and jeevatma becomes paramatma when it is purified. he says that this world is not mitya.

Madvacharya said: The jeevatma and paramatma are never identical(which makes me sad lol) and liberation can be achieved only though the grace of god.

Why each acharya condemn the other? They are the all knowing scholars then why did they have different perceptions of god?Whom should we follow?
To me Visistadvaita is more appealing.
