Explanation:

"The Raven" is a poem by Edgar Allan Poe, first published in 1845. The poem is known for its use of elements of musicality, supernatural environment and the language.

The speaker of the poem is lamenting over the lost o his lover, whose name is 'Lenore'. The theme of grief, and loss can be found in the poem. The raven who was sitting 'on the bust of Pallas' signifies this theme. He creates more tension to the on-going suffering of the speaker by repeating words "Nevermore."

This given excerpt is taken from stanza 14 of the poem, in this stanza, the speaker is hallucinating. In his hallucination, he imagines, that the air is becoming darker and denser with the 'perfume from an unseen censer'. And that the censer was held by an angel sent from God. He thinks that it is well for him to drink this potion, so overcome the grief of loss of his love. And this might help him to forget Lenore.

So, the theme that's been displayed in this stanza is "Grief and enmity".
