displacement in the brain, though, by the reaction of the physical upon the mental which I have spoken of above, the formation of thought-channels in the grey matter of the brain may tend to facilitate the reception of certain ideas. Some people are actually conscious of the action of the upper portion of the brain during the influx of an intuition, the sensation being that of a sort of expansion in that brain area, which might be compared to the opening of a valve or door; but all attempts to induce the inflow of intuitive ideas by the physiological expedient of trying to open this valve by the exercise of the will should be discouraged as likely to prove injurious to the brain. I believe some Oriental systems advocate this method, but we may well trust the mind to regulate the action of its physical channels in a manner suitable to its own requirements, instead of trying to manipulate the mind by the unnatural forcing of its mechanical instrument. In all our studies on these lines we must remember that development is always by perfectly natural growth and is not brought about by unduly straining any portion of the system.

The fact, however, remains that the intuition works most freely in that direction in which we most habitually concentrate our thought; and in practice it will be found that the best way to cultivate the intuition in any particular direction is to meditate
