So straw dogs were actual little dogs made out of straw that the Chinese used in rituals. After the rituals were over, the figurines were tossed. So here, the TTC is telling us that the Tao looks at people and all living things the same way. Some might say, "Whoa, that's kinda harsh. Don't I matter?" But a Taoist would see this as a lesson in humility. Our lives come and go, and the less value we place on ourselves, the closer we become to the Tao.
