Just as each soul spark of every living cell in our bodies makes up that which we call our soul, so too do all living souls in the world cumulatively make up part of a universal soul. Indeed, mysticism teaches us that the soul giving us vitality is connected to, and draws sustenance from, a universal soul.
You can visualize God's light each day and send it to someone who needs help. Your divine nature must reach out and touch the divine nature of another. Within you is the light of the world. It must be shared with the world.
