The previous canto (SB.3) concludes the dialogue between Maitreya Muni and Mahātmā Vidura regarding the instructions of Sri Kapiladeva to His mother, Devahūti, on the system of Sāṅkhya philosophy.
In the final chapter of the previous canto (SB.3.33), Devahūti, adhering to the instructions received from her son, practiced bhakti-yoga in samādhi, and in due course gave up her body; “the material elements of her body have melted into water and are now a flowing river, which is the most sacred of all rivers.”1
Śrī Maitreya said [a benediction]: “The description of the dealings of Kapiladeva and His mother is very confidential, and anyone who hears or reads this narration becomes a devotee of the Supreme Personality of Godhead, who is carried by Garuḍa, and he thereafter enters into the abode of the Supreme Lord to engage in the transcendental loving service of the Lord.” [SB.3.33.37]
