The time at which the seances are held is not in itself important, but it will be found best to fix such time at such an hour that will be most convenient for the sitters, and at which their minds will not be distracted by thoughts that they should return home, or should be attending to certain household or business duties, etc. The seances should be held not oftener than, say, twice a week, or at the most three times a week. Each seance should be continued for about an hour or a little over--certainly not over two hours at a time. The sitters should be punctual in attendance, so that no time may be lost or wasted. The idea should be that the spirit friends are awaiting your coming to fulfill your engagement with them, and one should be as careful to keep such an engagement as he would were the engagement with his most valued friend or esteemed acquaintance. Regularity in attendance is also important, as it is important that so far as possible the same general conditions be maintained at each and every seance. The seance should be started at the same hour on each occasion, at least so far as is possible, so as to preserve the same time rhythm. Opening of the Seance. It will be well to open the seance with a few moments of earnest, silent meditation--a few moments of dwelling "in the silence," as some have well called it; and these moments should be observed in a religious and devotional state of mind, all frivolity and flippancy being carefully avoided. If some present feel moved to prayer, then by all means let the prayer be made, for there can scarcely be a more fitting occasion for reverent prayer than a properly conducted seance. A few moments of hymn-singing may also be found advantageous in the direction of producing the devotional state of mind on the part of the sitters. The sitters should preserve a solemn frame of mind and reverent general demeanor during the seance--perhaps the best model is that of an old time Quaker Meeting in which the silent devout spiritual feeling was so plainly manifest that it could almost be felt physically. Patience is necessary in conducting a seance, and perseverance is essential. The manifestations cannot be unduly forced, and there is often required a great deal of psychical adjustment before the lines of the spiritual communication between the two great planes of life are fully established.
