"Our sense organs - our skin, eyes, ears, nose, and so on - connect us with the physical world. Those who neglect to make use of them are extremely limited in what they are able to do. What is true for the physical plane is also true for the spiritual plane: anyone who has not developed the organs that are meant to bring them into contact with the spiritual world has no means of knowing that world or of doing their work. Unfortunately, this is the case for the majority of humans: they have not yet developed these organs, and since they have not seen or felt anything of the spiritual world they believe they are entitled to say it does not exist. Scientific equipment has shown for a long time now that there are countless sound and light vibrations beyond our perception, and that is something nobody dares deny. Why then deny the reality of the spiritual world without having sought to study it?

Human beings are limited in their perceptions but how much more so in their reasoning! It is time they decided to go beyond their limits, as denying the existence of what they cannot see with their eyes or hear with their physical ears can only hold back their evolution."
