“Seth material” search engine (Jane Roberts)

Ruburt suddenly found himself then exploring very strange grounds indeed—and without the earlier sustaining hope. For all the recognized systems were wanting. He did not have to examine each one minutely, for his abilities, after some familiarization, left him with the knowledge of their merits. The stated discernible hypotheses of the various systems are one thing—but their invisible root assumptions are something else. Ruburt tried to put his understanding to practical use in terms of daily life, your relationship, work, finances, his classes, yet he found himself with definite physical hassles. You have encountered them through your relationship with him. In certain areas you both have blazed ahead. Those deeply seated, invisible, cultural assumptions still operated, however. Some of them you both dismissed for the very simple reason that they never temperamentally suited you to begin with. Others you dismissed because you grew in wisdom.

The symptoms were based then on beliefs that he accepted—beliefs that are all quite basic in your civilization, invisibly entwined in all of those systems he thought he had dismissed.
