The moment untruthfulness asserts itself, the super-sensible experiences fade away without being understood. People are never willing to believe this, but it is a fact.The first requirement for understanding the super-sensible world is the most scrupulous veracity in regard to the experiences of the senses. Those who are not strictly accurate about these experiences can have no true understanding of the super-sensible world. However much may be heard about the super-sensible world, it remains so much empty verbiage if the strictest conscientiousness is not present in formulating what happens here in the physical world.
Anyone who observes how humanity is handling palpable truth today will have a sorrowful picture! For most people are not in the least concerned to formulate something they have experienced in such a way that the experience is presented faithfully; their concern is to formulate things as they want them to be, in the way that suits themselves. They know nothing about the impulses that are at work to beguile them in one direction or another away from a faithful presentation of the physical experience.
