Explanation:"The Turtle" is a poem by author Mary Oliver. The speaker in the poem talks of the beauty and effortlessness of turtle laying eggs in the sand. It's a sacred action, which the turtle itself cannot understand since the drive to do it does not come consciously. It is a purely instinctive drive, guided by nature. The speaker admires the turtle's determination and patience in completing the task while remaining unaware of itself as an individual. The turtle sees itself as the world, and the world as itself.
