Then the woman turned her face to me and looked into my eyes without speaking. And through me passed a thrill, mysterious and penetrating like a golden wave; tones vibrated in my brain, a flame was in my heart, and I understood that she spoke to me, saying without words:
"This is the Hall of Wisdom. No one can reveal it, no one can hide it. Like a flower it must grow and bloom in thy soul. If thou wouldst plant the seed of this flower in thy soul — learn to discern the real from the false. Listen only to the Voice that is soundless... Look only on that which is invisible, and remember that in thee thyself, is the Temple and the gate to it, and the mystery, and the initiation."
