adhīyanta - they have learned; vyāsa-śiṣyāt - from the disciple of Vyāsadeva (Romaharṣaṇa); saṁhitām - the collection of the Purāṇas; mat-pituḥ - of my father; mukhāt - from the mouth; eka-ekām - each learning one portion; aham - I; eteṣām - of these; śiṣyaḥ - the disciple; sarvāḥ - all the collections; samadhyagām - I have thoroughly learned.

Each of them studied one of the six anthologies of the Purāṇas from my father, Romaharṣaṇa, who was a disciple of Śrīla Vyāsadeva. I became the disciple of these six authorities and thoroughly learned all their presentations of Purāṇic wisdom.
