“Enq: This is very interesting. Tell me, have the Adepts thus inspired or dictated to many of your Theosophists?
Theo: No, on the contrary, to very few. Such operations require special conditions. An unscrupulous but skilled Adept of the Black Brotherhood (“Brothers of the Shadow”, and Dugpas, we call them) has far less difficulties to labour under. For, having no laws of the Spiritual kind to trammel his actions, such a Dugpa “sorcerer” will unceremoniously obtain control over any mind, and subject it entirely to his evil powers.
But our Masters will never do that. They have no right, except by falling into Black Magic, to obtain full mastery over anyone’s immortal Ego, and can therefore act only on the physical and psychic nature of the subject, leaving thereby the free will of the latter wholly undisturbed.
Hence, unless a person has been brought into psychic relationship with the Masters, and is assisted by virtue of his full faith in, and devotion to, his Teachers, the latter, whenever transmitting their thoughts to one with whom these conditions are not fulfilled, experience great difficulties in penetrating into the cloudy chaos of that person’s sphere. But this is no place to treat of a subject of this nature.
Suffice it to say, that if the power exists, then there are Intelligences (embodied or disembodied) which guide this power, and living conscious instruments through whom it is transmitted and by whom it is received. We have only to beware of black magic.
Enq: But what do you really mean by “black magic”?
Theo: Simply abuse of psychic powers, or of any secret of nature; the fact of applying to selfish and sinful ends the powers of Occultism.
A hypnotizer, who, taking advantage of his powers of “suggestion”, forces a subject to steal or murder, would be called a black magician by us. The famous “rejuvenating system” of Dr. Brown-Sequard, of Paris, through a loathsome animal injection into human blood – a discovery all the medical papers of Europe are now discussing – if true, is unconscious black magic.”
