My friend, blood shaking my heart The awful daring of a moment’s surrender
The reference to The White Devil speaks of infidelity, and the carnal crimes that arise from ego and earthly passion. Hindu philosophy implies that these deeds arise from a misunderstanding of the partition between the physical and spiritual - those who commit such crimes and are swayed by physical passion do so because they are spiritually incomplete. The passage in general (white devil) reminds me of The Cenci, a play on a similar theme by Percy Shelley. The play also speaks of the corruptibility of spirit, and that carnal strife can only lead to more physical impurity and spite. The main character, Beatrice, claims that she "has eyes full of blood" after having been corrupted by the evil of her father, the Count Cenci - this corruption eventually leads her to kill him in his sleep. A similar web of desire and vice decimates the Cenci family as is present in The white devil.
