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.
The heights of the spirit can only be climbed by passing through the portals of humility. You can only acquire right knowledge when you have learnt to esteem it.
