Answer: I believe the best options to be "divinely inspired" and "dangerous toward others".
Explanation:
In the poem by Samuel Taylor Coleridge, the character Kubla Khan arrives at a magnificent place, a dome full of contrasts such as sunlight and ice caves. In such dome, nature is rough, dangerous, but marvelous and nurturing at the same. In the final stanza, the speaker's identity is mixed to that of Kubla Khan's. The speaker seems to desire to recreate the dome found by Khan, for he has "drunk the milk of Paradise". Even though his inspiration seems to come from the Heavens, Khan's (and the speaker's) persona becomes one that inspires awe, even terror - "Beware! His flashing eyes, his floating hair!". That's why people should "weave a circle round him thrice". It's a superstitious act in order to create protection against evil.
From that interpretation, we may conclude that these lines suggest that the poet, when caught up in the act of creation, is both divinely inspired and dangerous toward others.
