What is the critical thinking on Stopping by Woods on a Snowy Evening?

The poem deals with many themes, and its attention is focused on the speaker's infatuation with nature and the natural world he wants to be a part of. When we read the poem for the first time, we realize it is quite straightforward on the surface. The speaker  presumably passes through the woods in a horse-drawn carriage and stops to admire the winter evening scenery. He seems captivated by the woods filling up with snow.

The poem deals with many themes, and its attention is focused on the speaker's infatuation with nature and the natural world he wants to be a part of. When we read the poem for the first time, we realize it is quite straightforward on the surface. The speaker  presumably passes through the woods in a horse-drawn carriage and stops to admire the winter evening scenery. He seems captivated by the woods filling up with snow. 

Nevertheless, metaphorically speaking, the woods may represent a fantasy world, which the speaker yearns for. He desires to belong in it as opposed to the civilized world of promises and obligations which he hesitates to go back to. The world of wilderness both calms him and puzzles him, and the speaker wishes he could remain in it for a long time. Yet, he knows that he has not fulfilled all the obligations in his everyday world and that he must return to it because he has "promises to keep and miles to go before" he "sleeps." The verb "sleep" may symbolically refer to death, which may be embodied by this world of wilderness. The reason why this is plausible is because the speaker refers to the woods as "lovely, dark and deep," with the last two adjectives being reminiscent of death. Death is often depicted in terms of darkness, depth and mystery, so it is not impossible to think about the woods in terms of death.
