“In that tree’s forest, there’s a circle [of trees] eight fathoms in size, a circle nine fathoms in size … ten fathoms … fifteen fathoms in size. Only the elephant king Susaṃsthita was within a circle sixteen fathoms in size around the sal tree king. When those other 8,000 sal trees drop their limbs and leaves, a cool breeze blows through the forest from outside. Also, when the other 8,000 elephants defecate and urinate, yakṣas remove it from the forest.”
