tam talu-mulam pradahantam agnivad
gopala-sunum pitaram jagad-guroh
caccharda sadyo ’tirusaksatam bakas
tundena hantum punar abhyapadyata
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Krsna, who was the father of Lord Brahma but who was acting as the son of a cowherd man, became like fire, burning the root of the demon’s throat, and the demon Bakasura immediately disgorged Him. When the demon saw that Krsna, although having been swallowed, was unharmed, he immediately attacked Krsna again with his sharp beak.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Although Krsna is always as soft as a lotus, within the throat of Bakasura He created a burning sensation of being hotter than fire. Although Krsna’s whole body is sweeter than sugar candy, Bakasura tasted bitterness and therefore immediately vomited Krsna up. As stated in Bhagavad-gita (4.11), ye yatha mam prapadyante tams tathaiva bhajamy aham. When Krsna is accepted as an enemy, He becomes the most intolerable object for the nondevotee, who cannot tolerate Krsna within or without. Here this is shown by the example of Bakasura.
