Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
When the invincible Supreme Personality of Godhead, Krsna, heard the demigods crying “Alas! Alas!” from behind the clouds, He immediately enlarged Himself within the demon’s throat, just to save Himself and the cowherd boys, His own associates, from the demon who wished to smash them.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Such are the acts of Krsna. Paritranaya sadhunam vinasaya ca duskrtam (Bg. 4.8). By enlarging Himself within the throat of the demon, Krsna suffocated and killed him and at the same time saved Himself and His associates from imminent death and also saved the demigods from lamentation.
