"Neither," the Mahatma answered. "It is simply knowledge. Any one can do it, who knows how."
One of the men approached the fire again. He sat down on it, and went through the motions of bathing himself in the white-hot flame, turning his head repeatedly to grin at us. Then, lying down full-length, he rolled from end to end of the furnace, and walked away at last as casually as if he had come out of a bath. It was perfectly astonishing stuff to watch.
"If this isn't superstition, or mesmerism, or deception of some kind, why do you insist on all this mummery of soot and ashes for my friend and me?" King demanded. "Why do you use a temple full of Hindu idols to conceal your science, if it is a natural science and not trickery?"
The Gray Mahatma smiled tolerantly.
"Can you suggest a better way of keeping the secret?" he answered. "We are protected by the superstition. Not even the Government of India would dare arouse the superstitious wrath of a people by inquiring too closely into what goes on beneath a temple. If we were to admit that what we know is science, just as wireless telegraphy is a science, we would not be safe for an hour; the military, the kings of commerce, the merely curious, and all the enemies of mankind would invent ten thousand excuses of investigating us."
"Where did you learn English?" King demanded.
"I am a Ph.D. of Johns Hopkins," the Gray Mahatma answered. "I have traveled all over the United States seeking for one man who might be trusted with the rudiments of our science. But I found none."
"Suppose you had found the wrong man—and trusted him?" King suggested.
"My friend," said the Gray Mahatma, "you are better known to us than we to you. You are a man incapable of treachery. You love India, and all your life you have striven to act always and in all things like a man. You have been watched for years. Your character has been studied. If our purpose had been to conquer the world, or to destroy the world, we would never have selected you. There is no need to speak to you of what would happen if you should commit treachery. There is no risk of your explaining the secret of our science to the wrong individual, for you are not going to be taught it."
"Well, what of my friend Ramsden?" King asked him.
