Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
When annihilation is performed by the flames and sparks emanating from your eyes, the entire creation is burned to ashes. Nonetheless, you do not know how this happens. What then is to be said of your destroying the Daksa-yajña, Tripurasura and the kalakuta poison? Such activities cannot be subject matters for prayers offered to you.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Since Lord Siva considers the great acts he performs to be very unimportant, what was to be said of counteracting the strong poison produced by the churning? The demigods indirectly prayed that Lord Siva counteract the kalakuta poison, which was spreading throughout the universe.
