A true expert will know his metals, or metal, and his client, before commencing his magical work. Those persons who derive most virtue from a Talisman are those who belong to the most sensitive, or interior state, within such degree of life, and who are dominated by one sign only. Thus, if we find one sign occupying the whole of the House of Life, or practically so, as when the first face of a sign ascends, we may be sure, other things not interfering, that such a native will receive great benefit from wearing its Talismanic gem. If a person of good intellectual powers and sensitive spirituality, be born when the lord of the ascendant occupies the RISING SIGN, as, for instance, Mars in Aries, or Sun in Leo, we may be sure that, the Talismanic gem, in their case, will be exceedingly powerful, because, all the Astro-physical conditions are then most favorable for the expression of natural forces, and, if worn upon, or near that part of the body which the sign rules, the power and influence is more powerful and beneficial. In wearing them, take them to you as a part of yourself, a part of your higher self, a thing to be heeded, listened to and obeyed. They will usually make their presence most pronounced when something arises to disturb the harmonious vibrations that naturally and quietly go on between the person and the interstellar spaces above. They are like the sensor and motor nerves--they never make their presence known, except, when danger encroaches. Having explained in what sense gems become talismanic, we have now to disclose the modus operandi--THE HOW.
