The word nivista means that Suta Gosvami drank the juice of Bhagavatam through his ears.
That is the real process of receiving Bhagavatam.
One should hear with rapt attention from the real person, and then he can at once realize the presence of Lord Krsna in every page.
The secret of knowing Bhagavatam is mentioned here.
No one can give rapt attention who is not pure in mind.
No one can be pure in mind who is not pure in action.
No one can be pure in action who is not pure in eating, sleeping, fearing and mating.
But somehow or other if someone hears with rapt attention from the right person, at the very beginning one can assuredly see Lord Sri Krsna in person in the pages of Bhagavatam.
