प्राहरत्कुलिशं तस्मा अमोघं परमर्दनः ।
सयानो न्यपतद्भूमौ छिन्नपक्ष इवाचलः ॥ १२ ॥
praharat-inflicted; kulisam-thunderbolt scepter; tasmai-unto him (Bali Maharaja); amogham-infallible; para-mardanah-Indra, who is expert in defeating the enemy; sa-yanah-with his airplane; nyapatat-fell down; bhumau-on the ground; chinna-paksah-whose wings have been taken away; iva-like; acalah-a mountain.
When Indra, the defeater of enemies, released his infallible thunderbolt scepter at Bali Maharaja with a desire to kill him, Bali Maharaja indeed fell to the ground with his airplane, like a mountain with its wings cut off.
In many descriptions in Vedic literature it is found that mountains also fly in the sky with wings. When such mountains are dead, they fall to the ground, where they stay as very large dead bodies.
