The first thing necessary in such matters [sex-dreams and emissions] is to be perfectly calm and refuse to be upset by these difficulties. If they rise one must take it that they do so in order to be worked out. If there is nothing in the waking consciousness to encourage the sex-difficulty, then these dreams or discharges without dream can only be a rising up of old dormant impressions in the subconscient. Such risings often take place when the 
Force is working in the subconscient to clear it. It is also just possible that the discharges may be due, especially where there are no dreams, to purely material causes, e.g. the pressure of undischarged urine or faecal matter on the bladder. But in any case the thing is not to be disturbed and to put a force or will on the sex-centre or sex-organ for these things to cease. This can be done just before sleeping – usually after a time if done regularly, it has an effect. A calm general pressure of Will or Force on the physical subconscient is to be put. The subconscient may be often obstinate in its continual persistence, but it can and does accommodate itself quickly or slowly to the will of the conscious being.
