Occultism is in its essence man's effort to arrive at a knowledge of secret truths and potentialities of Nature which will lift him out of slavery to his physical limits of being, an attempt in particular to possess and organise the mysterious, occult, outwardly still undeveloped direct power of Mind upon Life and of both Mind and Life over Matter. There is at the same time an endeavour to establish communication with worlds and entities belonging to the supraphysical heights, depths and intermediate levels of cosmic Being and to utilise this communion for the mastery of a higher Truth and for a help to man in his will to make himself sovereign over Nature's powers and forces. This human aspiration takes its stand on the belief, intuition or intimation that we are not mere creatures of the mud, but souls, minds, wills that can know all the mysteries of this and every world and become not only Nature's pupils but her adepts and masters. The occultist sought to know the secret of physical things also and in this effort he furthered astronomy, created chemistry, gave an impulse to other sciences, for he utilised geometry also and the science of numbers; but still more he sought to know the secrets of supernature. In this sense occultism might be described as the science of the supernatural; but it is in fact only the discovery of the supraphysical, the surpassing of the material limit, - the heart of occultism is not the impossible chimera which hopes to go beyond or outside all force of Nature and make pure phantasy and arbitrary miracle omnipotently effective. What seems to us supernatural is in fact either a spontaneous irruption of the phenomena of other-Nature into physical Nature or, in the work of the occultist, a possession of the knowledge and power of the higher orders or grades of cosmic Being and Energy and the direction of their forces and processes towards the production of effects in the physical world by seizing on possibilities of interconnection and means for a material effectuality. There are powers of the mind and the life-force which have not been included in Nature's present systematisation of mind and life in matter, but are potential and can be brought to bear upon material things and happenings or even brought in and added to the present systematisation so as to enlarge the control of mind over our own life and body or to act on the minds, lives, bodies of others or on the movements of cosmic Forces. The modern admission of hypnotism is an example of such a discovery and systematised application, - though still narrow and limited, limited by its method and formula, - of occult powers which otherwise touch us or imperfectly caught by a few; for we are all the time undergoing a battery of suggestion, thought-suggestions, impulse-suggestions, will-suggestions, emotional and sensational suggestions, thought-waves, life-waves that come on us or into us from others or from the universal Energy, but act and produce their effects without our knowledge. A systematised endeavour to know these movements and their law and possibilities, to master and use the power or Nature-force behind them or to protect ourselves from them would fall within one province of occultism: but it would only be a small part even of that province; for wide and multiple are the possible fields, uses, processes of this vast range of little-explored Knowledge.

In modern times, as physical Science enlarged its discoveries and released the secret material forces of Nature into an action governed by human knowledge for human use, occultism receded and was finally set aside on the ground that the physical alone is real and Mind and Life are only departmental activities of Matter. On this basis, believing material Energy to be the key of all things, Science has attempted to move towards a control of mind and life processes by a knowledge of the material instrumentation and process of our normal and abnormal mind and life functionings and activities; the spiritual is ignored as only one form of mentality. It may be observed in passing that if this endeavour succeeded, it might not be without danger for the existence of the human race, even as now are certain other scientific discoveries misused or clumsily used by a humanity mentally and morally unready for the handling of powers so great and perilous; for it would be an artificial control applied without any knowledge of the secret forces which underlie and sustain our existence. Occultism in the West could be thus easily pushed aside because it never reached its majority, never acquired ripeness and a philosophic or sound systematic foundation. It indulged too freely in the romance of the supernatural or made the mistake of concentrating its major effort on the discovery of formulas and effective modes for using supramental powers. It deviated into magic white and black or into a romantic or thaumaturgic paraphernalia of occult mysticism and the exaggeration of what was after all a limited and scanty knowledge. These tendencies and this insecurity of mental foundation made it difficult to defend and easy to discredit, a target facile and vulnerable. In Egypt and the East this line of knowledge arrived at a greater and more comprehensive endeavour: this ampler maturity can be seen still intact in the remarkable system of the Tantras; it was not only a many sided science of the supernormal but supplied the basis of all the occult elements of religion and even developed a great and powerful system of spiritual discipline and self-realisation. For the highest occultism is that which discovers the secret movements and dynamic supernormal possibilities of Mind and Life and Spirit and uses them in their native force or by an applied process for the greater effectivity of our mental, vital and spiritual being.

Occultism is associated in popular idea with magic and magical formulae and a supposed mechanism of the supernatural. But this is only one side, nor is it altogether a superstition as is vainly imagined by those who have not looked deeply or at all at this covert side of secret Nature-Force or experimented with its possibilities. Formulas and their application, a mechanisation of latent forces, can be astonishingly effective in the occult use of mind-power and life-power just as it is in physical Science, But this is only a subordinate method and a limited direction. For mind and life forces are plastic, subtle and variable in their action and have not the material rigidity; they need a subtle and plastic intuition in the knowledge of them, in the interpretation of their action and process and in their application,—even in the interpretation and action of their established formulas. An overstress on mechanisation and rigid formulation is likely to result in sterilisation or a formalised limitation of knowledge and, on the pragmatic side, to much error, ignorant convention, misuse and failure. Now that we are outgrowing the superstition of the sole truth of Matter, a swing backward towards the old occultism and to new formulations, as well as to a scientific investigation of the still hidden secrets and powers of Mind and a close study of psychic and abnormal or supernormal psychological phenomena, is possible and, in parts, already visible. But if it is to fulfil itself, the true foundation, the true aim and direction, the necessary restrictions and precautions of this line of inquiry have to be rediscovered; its most important aim must be the discovery of the hidden truths and powers of the mind-force and the life-power and the greater forces of the concealed spirit. Occult science is, essentially, the science of subliminal, the subliminal in ourselves and the subliminal in world-nature, and of all that is in connection with the subliminal, including the subconscient and the superconscient, and the use of it as part of self-knowledge and world-knowledge and for the right dynamism of that knowledge.

In one of its aspects, occult science is like a kind of chemistry applied to the play of forces and the structure of the worlds and and individual forms of the inner dimensions. Just as in the chemistry of Matter the manipulation of certain substances is not without danger, so too in the occult worlds the wielding of certain forces and contact with them involve risks which only a great self-control and an unshakable calm can render innocuous.

In another of its aspects, occult science is, for the individual seeker, like the discovery and exploration of unknown countries whose laws and customs one often learns at one's own cost. Some of these realms are even rather terrifying for the beginner, who finds himself surrounded by news and unexpected perils. However, most of these dangers are more imaginary than real, and if one faces them without fear they lose the greater part of their reality.

In any case, at all times it has been recommended that one should take up these studies only under a very reliable guide hoe can point out the paths to follow, put you on guard against dangers, whether illusory or not, and give protection when needed.

Thus it is difficult to give more details here about the science itself, except to say that the indispensable basis of occult studies is a recognition of the concrete and objective reality of the many states of being and the inner worlds, which is a psychological application of the theory of four-dimensional or multi-dimensional space.

Occult science could thus be defined as a concrete objectification, in the world of forms, of what spiritual disciplines teach from the purely psychological point of view. The two should complement each other for the perfection of self-development and integral action. Occult knowledge without spiritual discipline is a dangerous instrument, for the one who uses it as for others, if it falls into impure hands. Spiritual knowledge with out occult science lacks precision and certainty in its objective results; it is all powerful only in the subjective world. The two, when combined in inner or outer action, are irresistible and are fit instruments for the manifestation of the supramental power.
