the majority of the advanced students, he reflected, the Institute of Insight wasn't really too healthy a place. But it offered compensations. Middle-aged or past it on the average, financially secure, vaguely disappointed in life, they'd found in Dr. Al a friendly and eloquent guide to lead them into the fascinating worlds of their own minds. And Dr. Al was good at it. He had borrowed as heavily from yoga and western mysticism as from various orthodox and unorthodox psychological disciplines, and composed his own system, almost his own cosmology. His exercises would have made conservative psychiatrists shudder, but he was clever enough to avoid getting his flock into too serious mental difficulties. If some of them suffered a bit now and then, it made the quest of Total Insight and the thought that they were progressing towards that goal more real and convincing. And meeting after meeting Dr. Al came up with some intriguing new twist or device, some fresh experience to keep their interest level high.

"Always bear in mind," he was saying earnestly at the moment, "that an advance made by any member of the group benefits the group as a whole. Thus, because of the work done by our young pioneers this week I see indications tonight that the group is ready to attempt a new experiment ... an experiment at a level I frankly admit I hadn't anticipated you would achieve for at least another two months."

Dr. Ormond paused significantly, the pause underlining his words. There was an expectant stirring among the students.

"But I must caution you!" he went on. "We cannot, of course, be certain that the experiment will succeed ... in fact, it would be a very remarkable thing if it did succeed at a first attempt. But if it should, you will have had a rather startling experience! You will have seen a thing generally considered to be impossible!"

He smile reassuringly, stepping down from the lectern. "Naturally, there will be no danger. You know me well enough to realize that I never permit the group or individuals to attempt what lies beyond their capability."

Cavender stifled a yawn, blinked water from his eyes, watching Ormond walk over to a small polished table on the left side of the room in front of the rows of chairs. On it Mavis Greenfield had placed a number of enigmatic articles, some of which would be employed as props in one manner or another during the evening's work. The most prominent item was a small suitcase in red alligator hide. Dr. Ormond, however, passed up the suitcase, took a small flat wooden plate from the table and returned to the center of the room.

"On this," he said, holding up the plate, "there rests at this moment the air of this planet and nothing else. But in a minute or two—for each of you, in his or her world of subjective reality—something else will appear on it."

The students nodded comprehendingly. So far, the experiment was on familiar ground. Dr. Ormond gave them all a good-humored wink.

"To emphasize," he went on, "that we deal here with practical, down-to-earth, real matters ... not some mystical nonsense ... to emphasize that, let us say that the object each of you will visualize on this plate will be—a ham sandwich!"

There were appreciative chuckles. But Cavender felt a twinge of annoyance. At the moment, when along with fighting off fatigue he'd been trying to forget that he hadn't eaten since noon, Dr. Al's choice looked like an unfortunate one. Cavender happened to be very fond of ham.

"Now here," Ormond continued, putting the plate down, "is where this experiment begins to differ from anything we have done before. For all of us will try to imagine—to visualize as being on this plate—the same ham sandwich. And so there will be no conflict in our projections, let's decide first on just what ingredients we want to put on it." He smiled. "We'll make this the finest ham sandwich our collective imagination can produce!"

There were more chuckles. Cavender cursed under his breath, his mouth beginning to water. Suggestions came promptly.

"Mustard?" Dr. Ormond said, "Of course—Not too sharp though, Eleanor?" He smiled at Mrs. Folsom. "I agree! A light touch of delicate salad mustard. Crisp lettuce ... finely chopped gherkins. Very well!"

"Put it all on rye," Cavender said helplessly. "Toasted rye."

"Toasted rye?" Ormond smiled at him, looked around. "Any objections? No? Toasted rye it shall be, Wally. And I believe that completes our selection."

He paused, his face turning serious. "Now as to that word of caution I gave you. For three minutes each of you will visualize the object we have chosen on the plate I will be holding up before me. You will do this with your eyes open, and to each of you, in your own subjective reality, the object will become, as you know, more or less clearly discernible.

"But let me tell you this. Do not be too surprised if at the end of that time, when the exercise is over, the object remains visible to you ... does not disappear!"

There was silence for a moment. Then renewed chuckles, but slightly nervous ones, and not too many.

Dr. Ormond said sternly, "I am serious about that! The possibility, though it may be small tonight, is there. You have learned that, by the laws of Insight, any image of subjective reality, if it can be endowed with all the attributes of objective reality by its human creator, must spontaneously become an image in objective reality!

"In this case, our collective ham sandwich, if it were perfectly visualized, could not only be seen by you but felt, its weight and the texture of each of its ingredients perceived, their appetizing fragrance savored"—Cavender groaned mentally—"and more: if one of you were to eat this sandwich, he would find it exactly as nourishing as any produced by the more ordinary methods of objective reality.

"There are people in the world today," Dr. Ormond concluded, speaking very earnestly now, "who can do this! There always have been people who could do this. And you are following in their footsteps, being trained in even more advanced skills. I am aware to a greater extent than any of you of the latent power that is developing—has developed—in this group. Tonight, for the first time, that power will be focused, drawn down to a pinpoint, to accomplish one task.

"Again, I do not say that at the end of our exercise a ham sandwich will lie on this plate. Frankly, I don't expect it. But I suggest very strongly that you don't let it surprise or startle you too much if we find it here!"

There was dead stillness when he finished speaking. Cavender had a sense that the lecture room had come alive with eerie little chills. Dr. Ormond lifted the plate solemnly up before him, holding it between the fingertips of both hands.

"Now, if you will direct your attention here ... no, Eleanor, with your eyes open!

"Let us begin...."

Cavender sighed, straightened up in his chair, eyes fixed obediently on the wooden plate, and banned ham sandwiches and every other kind of food firmly from his thoughts. There was no point in working his appetite up any further when he couldn't satisfy it, and he would have to be on guard a little against simply falling asleep during the next three minutes. The cloudiness of complete fatigue wasn't too far away. At the edge of his vision, he was aware of his fellow students across the room, arranged in suddenly motionless rows like staring zombies. His eyelids began to feel leaden.

The three minutes dragged on, came to an end. Ormond slowly lowered his hands. Cavender drew a long breath of relief. The wooden plate, he noted, with no surprise, was still empty.

"You may stop visualizing," Ormond announced.

There was a concerted sighing, a creaking of chairs. The students came out of their semitrances, blinked, smiled, settled into more comfortable positions, waiting for Dr. Al's comments.

"No miracles this time!" Ormond began briskly. He
