Co-operation is a grand incentive to labor; it also bringeth strength and courage to those who are united by its shining bands. It is the creator of harmony, sympathy, and fraternity of feeling in the hearts of all whom it reaches. Under its beautiful and effective ministrations, humanity is destined to grow and unfold its highest powers and attributes until universal love and tenderness bloom in all hearts, and every soul, of every race and clime, becomes united in a heavenly band of brotherhood and sisterhood. CARE AND PROTECTION OF MEDIUMS. One of our extensive co-operative societies is composed of young ladies whose duties are to study the laws governing mediumship, as well as to gain an understanding of those electric forces operating between spirit and matter, of which certain spirits take advantage in manifesting their presence to mortals. Realizing the grievous error concerning immortal life in which the larger portion of mankind is plunged, and wishing to do all in their power to demonstrate the truth to humanity, so that doubt may give way to certainty, fear to confidence, ignorance to knowledge, and all hearts made glad with the soul-cheering conviction that there is no death, but that life is eternal, these spirits have joined together for the purpose of working in harmony for the promotion of spiritual truth upon the earth. Singly, in pairs, or in groups, the young people of this society visit the various mediums of earth to supply them with magnetic power and spiritual strength. They draw around each of those sensitive instruments an ethereal garment woven from the elements of their (the spirits’) own lives, which, like a mantle of light, protects the mediums from the poisonous arrows of persecution, scorn, and envy hurled against them by malicious or distrustful minds, and guards them in their labor of love for the angels. Spirits are well aware that thoughts are tangible things that can be both seen and felt, and can wound or heal the sensitive souls to whom they are directed, according to their blighting or beneficent character. Thus, when one is envious or in any manner hostile in feeling to another, the thoughts which he directs toward that person, charged as they are with the virile magnetism the exercise of hatred or any other passion engenders, strike upon the spirit of him to whom they are directed with stinging effect. If the individual of whom this person happens to think unkindly or severely is one susceptible to spiritual and other influences,—kept in a negative condition because of the frequent control of his organism by spirits,—he will keenly sense the silent shafts of thought hurled against him, and suffer in consequence. Many mediums experience mental and physical pain, as well as debility of power, frequently when they are unaware of the cause; while at the very time some person, who is antagonistic to them and their work, is
