This same verse and other very similar verses occur elsewhere in the Śrīmad-Bhāgavatam: Third Canto, Chapter Twenty-seven, verse 4; Fourth Canto, Chapter Twenty-nine, verses 35 and 73; and Eleventh Canto, Chapter Twenty-two, verse 56. In fact, this verse completely explains the essence of illusion.
