This short passage, taken from Baha’u’llah’s Tablet known as the “Seven Valleys” tells of a beautiful spiritual idea, that human hearts- like mirrors- should be kept clean to reflect the light of goodness and truth. A mirror that has dirt on it can not reflect light- “light” in this instance meaning the “light of God”- spiritual truth and goodness. The “dirt” are our “worldly attachments”- things that we are attached to, but actually keep us tethered and don’t allow us to grow. Attachments come in many forms- often consisting of various forms of ego or unhealthy emotional attachment- that keep us from seeing and reflecting truth.
