pravartate yatra rajas tamas tayoḥ
sattvaḿ ca miśraḿ na ca kāla-vikramaḥ
na yatra māyā kim utāpare harer
anuvratā yatra surāsurārcitāḥ
This verse from Srimad-Bhagavatam (2.9.10) was spoken by Srila Sukadeva Gosvami. He was answering the questions of Parikshit Maharaja, who asked how the living entity falls down into the material world. Sukadeva Gosvami explained the cream of Srimad-Bhagavatam in four verses, which had been explained to Lord Brahma at the end of the severe austerities he performed for one thousand celestial years. At that time, Brahma was shown the spiritual world and its transcendental nature.
