Thought linked with will undergoes a certain maturing if we permit ourselves never to be robbed by previous experiences of the unbiased receptivity for new experiences. For the student of the spiritual the following thought should entirely lose its meaning, “I have never heard that, I do not believe that.” It should be his aim, during specific periods of time, to learn something new on every occasion from everything and everybody. From every breath of air, from every leaf, from the babbling of children one can learn something if one is prepared to bring to one’s aid a certain point of view that one has not made use of up to the present. It will, however, be easily possible in regard to such an ability to go wide of the mark. One should not in any way disregard, at any particular stage of life, one’s previous experiences. One should judge what one experiences in the present by one’s experiences of the past. This is placed upon one scale of the balance; upon the other, however, must be placed the inclination of the student continually to experience the new. Above all, there must be faith in the possibility that new experiences may contradict the old.
