"Does OOB vision follow the laws of OPTICS? On the high self we arranged stimulus material (for example a small letter 'd') inside a closed box with a small opening and a twomirror system. "We wanted to see whether in the OOB state Mr. Swann could see the target through the opening, as he would normally see it from that point (as reflected via the mirror), or whether he would see it directly by clairvoyance, without using the mirrored image. "On the basis of our [successful] preliminary results, we are now developing sophisticated optical systems for testing the ecsomatic hypothesis of OOBE. Several physicists, engineers and psychologists are enthusiastically cooperating [names given at the end of this longish quote.] "PHYSIOLOGY: What is happening to Ingo Swann's body at the times when he feels his spiritual self to be somewhere else? We have accumulated a considerable mass of physiological records, now in process of analysis. "The autonomic nervous system responses seem quite within normal range, indicating that there is no danger to the organism during OOB states.
