“While sacred and authoritative, adjustments
that are made in consideration of time and circumstance are not viewed
as deviant. The Puranas, after all, are literature that seeks to
present the essence of the Veda in an easily understandable format. To
accomplish this task, the Puranic literature must be fluid. Such
fluidity, however, does not amount to interpolation, but rather attests
to the ongoing nature of revelation. This also explains why it is
particularly difficult to assign a date to the authorship of the
Bhagavatam. When was it written? The correct answer is perhaps that it
is not finished yet.” – Swami BV Tripurari

The difference between living scripture and static. Quite a revelation.
