49. The Practical Training of Thinking
So for anyone who wants to penetrate into these spiritual worlds, who, so to speak, wants to acquire clairvoyant consciousness, the right foundation is not enthusiasm, not overheated enthusiasm, but for them the right foundation is to stand firmly on the ground of life with both feet. One would almost like to say, although it may sound grotesque, that the less a person approaches spiritual research with overheated imagination and reveries and fantasies, the better it is.

Then we are already raised to the poetic, enthusiastic attitude by the facts, and that is what is healthy — not by letting an overheated inner self bring us to enthusiasm.
