Rudolf Steiner

For the attainment of knowledge and proficiency in the higher worlds, there is no obstacle for those who earnestly seek them.

The clairvoyant must not become a visionary; he must retain a firm footing upon the earth.

The golden rule [for spiritual science] is as follows: For every one step that you take in the pursuit of higher knowledge, take three steps in the perfection of your character.

Courage and self-confidence are two beacons which must never be extinguished on the path to higher knowledge. No one will ever travel far who cannot bring himself to repeat, over and over again, an exercise which has failed, apparently, for a countless number of times.

A mere intellectual understanding of what is included in these attributes is of no value. They must be so incorporated into the soul that they form the basis of inner habits.

He does not learn in order to accumulate learning as his own treasure, but in order that he may devote his learning to the service of the world.

The student is impervious to all influences which would divert him from the goal he has set for himself, as long as he can regard it as the right goal. For him, obstacles contain a challenge that impels him to surmount them, but never a reason for giving up.
