एष देव दितेर्गर्भ ओज: काश्यपमर्पितम् । दिशस्तिमिरयन् सर्वा वर्धतेऽग्निरिवैधसि ॥ १० ॥
eṣa deva diter garbha ojaḥ kāśyapam arpitam diśas timirayan sarvā vardhate ’gnir ivaidhasi
O gods, this embryo in Diti’s womb, formed from the potent seed of Kaśyapa, is growing like fire fed by fuel, casting darkness over all directions.
The darkness throughout the universe is explained herewith as being caused by the embryo created in the womb of Diti by the semen of Kaśyapa.
This verse describes Diti’s embryo as a fierce, expanding potency that darkens the directions—an omen of disruptive, demonic influence increasing in the universe.
Seeing the ominous rise of destructive power connected with Diti’s pregnancy, the devas appeal to Viṣṇu—the maintainer of cosmic order—for protection and restoration of dharma.
Unchecked negative tendencies grow when continually “fed”; the verse cautions seekers to stop supplying fuel to harmful habits and instead take shelter of sattvic discipline and devotion.
