If I may make another suggestion, it would be that those who have psychic awakening should think twice before proclaiming the fact. It is a new sense that is coming into manifestation; but as the opening of the eyes in an early stage of evolution probably revealed as many dangers as blessings, so the new sense will reveal dangers. Do not try to close the new sense, but do not be carried away by it. Remember that it will be practically general, and like every new sense it will be defective for a long time. It will reveal false things as well as true. If a man opened his eyes for the first time upon a harmless tree, he might mistake it for a monster. Restraint in all things, moderation in all things, even in the laudable desire to action. Weigh and measure. Prove before accepting anything--prove by reason and by intuition if you cannot wait for proof by practice. Weigh and measure what I say, as well as what the wildest new prognosticator says. Discourage hysteria. A wave of hysteria is likely to sweep over the world. As revolution follows revolution, the startled inhabitants of the world may tell themselves that nothing in the universe is stable, that all is going to destruction, and that as they cannot save themselves from what seems to be universal chaos, they may as well get all the pleasurable excitement possible out of the passing moment. Restraint, restraint! I see women afraid to bear children because of the uncertainty of the morrow. I see men afraid to marry because of the uncertainty of domesticity. I see farmers hesitate to plant because of the uncertainty of the harvest. Again I say, be not afraid. If you sow, you shall reap. If you marry, you shall build a home. If you have children, the race will protect them--and you are a part of the race. Restraint! Fearlessness! LETTER VIII THE WORLD OF MIND _March 24, 1917._ I WISH that more people of sane, sound mind would experiment in telepathic communication. I know there is any amount of uncoordinated and half-serious playing with phenomena; but with scientific accuracy of observation and scientific precision in recording data, not only the body of _sensible_ literature on these subjects would be increased, but the habits of careful observation and precision in reporting supernormal facts would be developed in the experimentalists. You who write for me, continue to make and to record experiments. You are almost too cautious, but most persons are not cautious enough.
