Book 3, 1935:
"Now we may begin the approach to the Fiery World, affirming the Supermundane signs. We have repeatedly pointed out the urgency of the development of necessary earthly qualities. The Teaching always proceeds along two currents which, when they meet, form the complete line of attainment. While many earthly qualities are not easy to attain, the super-earthly conditions may appear to be abstract; but they are an existing reality. He who is accustomed to think on a planetary scale knows how real is the life in the World of Fire, in the World of Radiance, in the World of Attainment."
