1.3.36

vyāsena kṛtvātiśubhaṃ purāṇaṃ śukāya putrāya mahātmane yat |
vairāgyayuktāya ca pāṭhitaṃ vai vijñāya caivāraṇisambhavāya ||

O best Munis! Thus, compiling the Purânas Veda Vyâsa thought this Purâna to be the best; so (without teaching it to other persons) he settled that his own son the high-sould S’uka Deva born of the dry woods used for kindling fire (excited by attrition), having no passion for the worldly things, would be the fit student to be taught this Purâna and therefore taught him; at that time I was a fellow student along with S’aka Deva and I heard every thing from the mouth of Vyâsa Deva and realised th« secret meanings thereof. This has happened through the grace of the merciful Guru Veda Vyâsa.
Here ends the Third Chapter of S’rimad Devi Bhâgavatam on praising the Purânas and on each Vyâsa of every Dvâpara Yuga.
