There is no feeling and no enthusiasm to be compared with the sentiments of warmth, beauty and exaltation that are enkindled through the pure, crystal-clear thoughts that refer to the higher worlds. The highest feelings are, as a matter of fact, not those that come of themselves, but those that are achieved by energetic and persevering thinking.
