ວະຍາສະກ່າວວ່າ: ໃນການກ່ອນ ອະສຸຣະຜູ້ມີລິດເດດໄດ້ຄອບຄອງນະຄອນສາມແຫ່ງໃນຟ້າ. ແຫ່ງໜຶ່ງເຮັດດ້ວຍເຫຼັກ, ແຫ່ງໜຶ່ງເຮັດດ້ວຍເງິນ, ແລະແຫ່ງທີສາມ—ໃຫຍ່ຫຼວງຢ່າງຍິ່ງ—ເຮັດດ້ວຍຄໍາ.
व्यास उवाच
Material grandeur and seemingly impregnable power (cities of iron, silver, and gold) do not guarantee moral legitimacy or lasting security; narratives of the Asuras often use such splendor to highlight how pride and domination invite eventual ruin when opposed by dharma.
Vyāsa introduces an ancient account: the Asuras possessed three heavenly cities—one iron, one silver, and one enormous golden city—setting up a mythic background (commonly associated with the Tripura motif) that explains later divine or heroic action against them.
