PURPORT

Srila Bhaktisiddhanta Sarasvati Thakura states that without studying Srimad-Bhagavatam, one cannot understand the purport of Brahma-sutra (Vedanta-sutra) or the Upanisads. If one tries to understand Vedanta philosophy and the Upanisads without studying Srimad-Bhagavatam, he will be bewildered and, construing a different meaning, will gradually become an atheist or an impersonalist.
