It is cheap to say: Give me the means to see for myself. Actually, anyone can attain the means, provided that person seeks guidance of the right kind. Spiritual science constitutes such guidance and it is accessible to everyone. The very first requirement, however, is the ability to rise above the usual way of looking at things. The person must, as it were, say: Here is someone who tells me he can see into the spiritual world, and who relates many specific details. He speaks about what happens to humans after death, about spiritual forces and beings that are invisible to ordinary sight, and that permeate the world about us. As yet I cannot see that world, but if I keep an open mind and pay attention to my feelings and inner sense for Truth, I shall know whether what I hear sounds probable or the reverse. I can further apply logical thinking to the matter, and see if life itself bears out what I am told. Having listened calmly to everything and found nothing to contradict common sense, I shall attempt to look at the world in light of this knowledge and see if it explains human destiny. By assuming spiritual scientific views to be correct, I will be able to test whether they explain things and make life understandable. I shall also gradually discover if spiritual knowledge does give one inner strength, joy and confidence in life. In other words, I will discover whether there is a basis for accepting the words of the initiate. This attitude I adopt is the same in regard to spiritual knowledge as that adopted by a remarkable person in regard to the ordinary world of light and color.
