Answer:
Of bliss on bliss, while I to Hell am thrust,
Where neither joy nor love, but fierce desire,
Among our other torments not the least,
Step-by-step explanation:
John Milton's epic poem "Paradise Lost" is written in free verse, concerning the fall of man from the garden of Eden. It is based on the Biblical story of Adam and Eve in the garden of Eden, and the eventual deception by Satan.
The given excerpt in the question is from Book IV of the poem, where Satan seems to be rejoicing in his successful effort of deceiving Adam and Eve. But then again, he also felt sad about not being able to experience the love that Adam and Eve had. The three lines-
Of bliss on bliss, while I to Hell am thrust,
Where neither joy nor love, but fierce desire,
Among our other torments not the least,
shows his regret in not being able to feel the feeling of love. Though Adam and Eve were banned from the garden, they were still content with themselves for they have each other to depend on. This feeling of love that they felt is what Satan envies, thus exclaiming his regret over it.
