Boanerges

And neigh like Boanerges —

Then — punctual as a Star

Stop — docile and omnipotent

At its own stable door —

These lines are from a poem by Emily Dickinson titled "I taste a liquor never brewed." The poem describes the speaker's experience of being intoxicated, and the lines you have quoted suggest that the speaker feels as if they are riding a horse that is neighing loudly and powerfully like Boanerges, a biblical name meaning "son of thunder."

However, despite its wildness and power, the horse is also "punctual as a Star" and can stop and return to its stable door with perfect control and obedience.

The poem can be interpreted as a metaphor for the intoxicated experience in which powerful sensations and feelings carry the mind and body away. Still, it ultimately must return to a state of sobriety and control. The image of the horse suggests that this experience can be both exhilarating and dangerous and requires balance and self-awareness to appreciate and understand fully.

The poem can also be read as a celebration of the natural world and the power and beauty of animals and a reminder of how we are connected to the world around us.
