What you describe is the material consciousness; it is mostly subconscient, but the part of it that is conscious is mechanical, inertly moved by habits or by the forces of the lower nature. Always repeating the same unintelligent and unenlightened movements, it is attached to the routine and established rule of what already exists, unwilling to change, unwilling to receive the Light or obey the higher Force. Or, if it is willing, then it is unable. Or, if it is able, then it turns the action given to it by the Light or the Force into a new mechanical routine and so takes out of it all soul and life. It is obscure, stupid, indolent, full of ignorance and inertia, darkness and slowness of tamas.

It is this material consciousness into which we are seeking to bring first the higher (divine or spiritual) Light and Power and Ananda, and then the supramental Truth which is the object of our yoga.

It is the most physical consciousness of which you have become aware; it is like that in almost everyone: when one gets fully or exclusively into it, one feels it to be like that of an animal, either obscure and restless or inert and stupid and in either condition not open to the Divine. It is only by bringing the Force and higher consciousness into it that it can fundamentally alter. When these things show themselves do not be upset by their emergence, but understand that they are there to be changed.

Here as elsewhere, quiet is the first thing needed, to keep the consciousness quiet, not allow it to get agitated and in turmoil. Then in the quiet to call for the Force to clear up all this obscurity and change it.

 “At the mercy of the external sounds and external bodily sensations”, “no control to drop the ordinary consciousness at will”, “the whole tendency of the being away from yoga”—all that is unmistakably applicable to the physical mind and the physical consciousness when they isolate themselves, as it were, and take up the whole front, pushing the rest into the background. When a part of the being is brought forward to be worked upon for change, this kind of all-occupying emergence, the dominant activity of that part as if it alone existed very usually happens, and unfortunately it is always what has to be changed, the undesirable conditions, the difficulties of that part which rise first and obstinately hold the field and recur. In the physical it is inertia, obscurity, inability that come up and the obstinacy of these things. The only thing to do in this unpleasant phase is to be more obstinate than the physical inertia and to persist in a fixed endeavour—steady persistency without any restless struggle—to get a wide and permanent opening made even in this solid rock of obstruction.

These variations in the consciousness during the day are a thing that is common to almost everybody in the sadhana. The principle of oscillation, relaxation, relapse to a normal or a past lower condition from a higher state that is experienced but not yet perfectly stable, becomes very strong and marked when the working of the sadhana is in the physical consciousness. For there is an inertia in the physical nature that does not easily allow the intensity natural to the higher consciousness to remain constant,—the physical is always sinking back to something more ordinary; the higher consciousness and its force have to work long and come again and again before they can become constant and normal in the physical nature. Do not be disturbed or discouraged by these variations or this delay, however long and tedious; remain careful only to be quiet always with an inner quietude and as open as possible to the higher Power, not allowing any really adverse condition to get hold of you. If there is no adverse wave, then the rest is only a persistence of imperfections which all have in abundance; that imperfection and persistence the Force must work out and eliminate, but for the elimination time is needed.

You should not allow yourself to be discouraged by any persistence of the movements of the lower vital nature. There are some that tend always to persist and return until the whole physical nature is changed by the transformation of the most material consciousness; till then their pressure recurs—sometimes with a revival of their force, sometimes more dully—as a mechanical habit. Take from them all life-force by refusing any mental or vital assent; then the mechanical habit will become powerless to influence the thoughts and acts and will finally cease.

The Muladhar is the centre of the physical consciousness proper, and all below in the body is the sheer physical, which as it goes downward becomes increasingly subconscient, but the real seat of the subconscient is below the body, as the real seat of the higher consciousness (superconscient) is above the body. At the same time, the subconscient can be felt anywhere, felt as something below the movement of the consciousness and, in a way, supporting it from beneath or else drawing the consciousness down towards itself. The subconscient is the main support of all habitual movements, especially the physical and lower vital movements. When something is thrown out of the vital or physical, it very usually goes down into the subconscient and remains there as if in seed and comes up again when it can. That is the reason why it is so difficult to get rid of habitual vital movements or to change the character; for, supported or refreshed from this source, preserved in this matrix your vital movements, even when suppressed or repressed, surge up again and recur. The action of the subconscient is irrational, mechanical, repetitive. It does not listen to reason or the mental will. It is only by bringing the higher Light and Force into it that it can change.

The subconscient is universal as well as individual like all the other main parts of the Nature. But there are different parts or planes of the subconscient. All upon earth is based on the Inconscient as it is called, though it is not really inconscient at all, but rather a complete “sub”-conscience, a suppressed or involved consciousness, in which there is everything but nothing is formulated or expressed. The subconscient lies between this Inconscient and the conscious mind, life and body. It contains the potentiality of all the primitive reactions to life which struggle out to the surface from the dull and inert strands of Matter and form by a constant development a slowly evolving and self-formulating consciousness; it contains them not as ideas, perceptions or conscious reactions but as the fluid substance of these things. But also all that is consciously experienced sinks down into the subconscient, not as precise though submerged memories but as obscure yet obstinate impressions of experience, and these can come up at any time as dreams, as mechanical repetitions of past thought, feelings, action, etc., as “complexes” exploding into action and event, etc., etc. The subconscient is the main cause why all things repeat themselves and nothing ever gets changed except in appearance. It is the cause why people say character cannot be changed, the cause also of the constant return of things one hoped to have got rid of for ever. All seeds are there and all Sanskaras of the mind, vital and body,—it is the main support of death and disease and the last fortress (seemingly impregnable) of the Ignorance. All too that is suppressed without being wholly got rid of sinks down there and remains as seed ready to surge up or sprout up at any moment.

The sub-conscious is the evolutionary basis in us, it is not the whole of our hidden nature, nor is it the whole origin of what we are. But things can rise from the subconscient and take shape in the conscious parts and much of our smaller vital and physical instincts, movements, habits, character-forms has this source.

There are three occult sources of our action—the superconscient, the subliminal, the subconscient, but of none of them are we in control or even aware. What we are aware of is the surface being which is only an instrumental arrangement. The source of all is the general Nature,—universal Nature individualising itself in each person; for this general Nature deposits certain habits of movement, personality, character, faculties, dispositions, tendencies in us, and that, whether formed now or before our birth, is what we usually call ourselves. A good deal of this is in habitual movement and use in our known conscious parts on the surface, a great deal more is concealed in the other unknown three which are below or behind the surface.

But what we are on the surface is being constantly set in motion, changed, developed or repeated by the waves of the general Nature coming in on us either directly or else indirectly through others, through circumstances, through various agencies or channels. Some of this flows straight into the conscious parts and acts there, but our mind ignores its source, appropriates it and regards all that as its own; a part comes secretly into the subconscient or sinks into it and waits for an opportunity of rising up into the conscious surface; a good deal goes into the subliminal and may at any time come out—or may not, may rather rest there as unused matter. Part passes through and is rejected, thrown back or thrown out or spilt into the universal sea. Our nature is a constant activity of forces supplied to us out of which (or rather out of a small amount of it) we make what we will or can. What we make seems fixed and formed for good, but in reality it is all a play of forces, a flux, nothing fixed or stable; the appearance of stability is given by constant repetition and recurrence of the same vibrations and formations. That is why our nature can be changed in spite of Vivekananda's saying and Horace's adage and in spite of the conservative resistance of the subconscient, but it is a difficult job because the master mode of Nature is this obstinate repetition and recurrence.

As for the things in our nature that are thrown away from us by rejection but come back, it depends on where you throw them. Very often there is a sort of procedure about it. The mind rejects its mentalities, the vital its vitalities, the physical its physicalities—these usually go back into the corresponding domain of general Nature. It all stays at first, when that happens, in the environmental consciousness which we carry about with us, by which we communicate with the outside Nature, and often it persistently rushes back from there—until it is so absolutely rejected, or thrown far away as it were, that it cannot return upon us any more. But when what the thinking and willing mind rejects is strongly supported by the vital, it leaves the mind indeed but sinks down into the vital, rages there and tries to rush up again and reoccupy the mind and compel or capture our mental acceptance. When the higher vital too—the heart or the larger vital dynamis rejects it, it sinks from there and takes refuge in the lower vital with its mass of small current movements that make up our daily littleness. When the lower vital too rejects it, it sinks into the physical consciousness and tries to stick by inertia or mechanical repetition. Rejected even from there it goes into the subconscient and comes up in dreams, in passivity, in extreme tamas. The Inconscient is the last resort of the Ignorance.

As for the waves that recur from the general Nature, it is the natural tendency of the inferior forces there to try and perpetuate their action in the individual, to rebuild what he has unbuilt of their deposits in him; so they return on him, often with an increased force, even with a stupendous violence, when they find their influence rejected. But they cannot last long once the environmental consciousness is cleared—unless the “Hostiles” take a hand. Even then these can indeed attack, but if the sadhak has established his position in the inner self, they can only attack and retire.

It is true that we bring most of ourselves,—or rather most of our predispositions, tendencies of reaction to the universal Nature, from past lives. Heredity only affects strongly the external being; besides, all the effects of heredity are not accepted even there, only those that are in consonance with what we are to be or not preventive of it at least.
