If you rewrite the truth to fit you, then it is not the truth any more.
How do you know what is truth? I think it's fairly obvious that some of the Mahayana sutras have embezzled elements to them. To take them literally is to miss the point of the sutras. For instance the fact that I don't believe Avalokiteśvara existed or delivered the Heart Sutra doesn't in any way diminish the wisdom of that sutra.
