It is not possible to make a foundation in yoga if the mind is restless.The first thing needed is quiet in the mind. Also to merge the personal consciousness is not the first aim of the yoga: the first aim is to open it to a higher spiritual consciousness and for this also a quiet mind is the first need.

The first thing to do in the sadhana is to get a settled peace and silence in the mind. Otherwise you may have experiences, but nothing will be permanent. It is in the silent mind that the true consciousness can be built.

A quiet mind does not mean that there will be no thoughts or mental movements at all, but that these will be on the surface and you will feel your true being within separate from them, observing but not carried away, able to watch and judge them and reject all that has to be rejected and to accept and keep to all that is true consciousness and true experience.

Passivity of the mind is good, but take care to be passive only to the Truth and to the touch of the Divine Shakti. If you are passive to the suggestions and influences of the lower nature, you will not be able to progress or else you will expose yourself to adverse forces which may take you far away from the true path of yoga.

Aspire to the Mother for this settled quietness and calm of the mind and this constant sense of the inner being in you standing back from the external nature and turned to the Light and Truth.

The forces that stand in the way of sadhana are the forces of the lower mental, vital and physical nature. Behind them are adverse powers of the mental, vital and subtle physical worlds. These can be dealt with only after the mind and heart have become one-pointed and concentrated in the single aspiration to the Divine.

Silence is always good; but I do not mean by quietness of mind entire silence. I mean a mind free from disturbance and trouble, steady, light and glad so as to open to the Force that will change the nature. The important thing is to get rid of the habit of the invasion of troubling thoughts, wrong feelings, confusion of ideas, unhappy movements. These disturb the nature and cloud it and make it difficult for the Force to work; when the mind is quiet and at peace, the Force can work more easily. It should be possible to see things that have to be changed in you without being upset or depressed; the change is the more easily done.

The difference between a vacant mind and a calm mind is this: that when the mind is vacant, there is no thought, no conception, no mental action of any kind, except an essential perception of things without the formed idea; but in the calm mind, it is the substance of the mental being that is still, so still that nothing disturbs it. If thoughts or activities come, they do not rise at all out of the mind, but they come from outside and cross the mind as a flight of birds crosses the sky in a windless air. It passes, disturbs nothing, leaving no trace. Even if a thousand images or the most violent events pass across it, the calm stillness remains as if the very texture of the mind were a substance of eternal and indestructible peace. A mind that has achieved this calmness can begin to act, even intensely and powerfully, but it will keep its fundamental stillness—originating nothing from itself but receiving from Above and giving it a mental form without adding anything of its own, calmly, dispassionately, though with the joy of the Truth and the happy power and light of its passage.

It is not an undesirable thing for the mind to fall silent, to be free from thoughts and still—for it is oftenest when the mind falls silent that there is the full descent of a wide peace from above and in that wide tranquillity the realisation of the silent Self above the mind spread out in its vastness everywhere. Only, when there is the peace and the mental silence, the vital mind tries to rush in and occupy the place or else the mechanical mind tries to raise up for the same purpose its round of trivial habitual thoughts. What the sadhak has to do is to be careful to reject and hush these outsiders, so that during the meditation at least the peace and quietude of the mind and vital may be complete. This can be done best if you keep a strong and silent will. That will is the will of the Purusha behind the mind; when the mind is at peace, when it is silent one can become aware of the Purusha, silent also, separate from the action of the nature.

To be calm, steady, fixed in the spirit, dhira, sthira, this quietude of the mind, this separation of the inner Purusha from the outer Prakriti is very helpful, almost indispensable. So long as the being is subject to the whirl of thoughts or the turmoil of the vital movements, one cannot be thus calm and fixed in the spirit. To detach oneself, to stand back from them, to feel them separate from oneself is indispensable.

For the discovery of the true individuality and building up of it in the nature, two things are necessary, first, to be conscious of one's psychic being behind the heart and, next, this separation of the Purusha from the Prakriti. For the true individual is behind veiled by the activities of the outer nature.

A great wave (or sea) of calm and the constant consciousness of a vast and luminous Reality—this is precisely the character of the fundamental realisation of the Supreme Truth in its first touch on the mind and the soul. One could not ask for a better beginning or foundation—it is like a rock on which the rest can be built. It means certainly not only a Presence, but the Presence—and it would be a great mistake to weaken the experience by any non-acceptance or doubt of its character.

It is not necessary to define it and one ought not even to try to turn it into an image; for this Presence is in its nature infinite. Whatever it has to manifest of itself or out of itself, it will do inevitably by its own power, if there is a sustained acceptance.

It is quite true that it is a grace sent and the only return needed for such a grace is acceptance, gratitude and to allow the Power that has touched the consciousness to develop what has to be developed in the being—by keeping oneself open to it. The total transformation of the nature cannot be done in a moment; it must take long and proceed through stages; what is now experienced is only an initiation, a foundation for the new consciousness in which that transformation will become possible. The automatic spontaneity of the experience ought by itself to show that it is nothing constructed by the mind, will or emotions; it comes from a Truth that is beyond them.

To reject doubts means control of one's thoughts—very certainly so. But the control of one's thoughts is as necessary as the control of one's vital desires and passions or the control of the movements of one's body—for the yoga, and not for the yoga only. One cannot be a fully developed mental being even, if one has not a control of the thoughts, is not their observer, judge, master,— the mental Purusha, manomaya purusa, saksi, anumanta, isvara. It is no more proper for the mental being to be the tennis-ball of unruly and uncontrollable thoughts than to be a rudderless ship in the storm of the desires and passions or a slave of either the inertia or the impulses of the body. I know it is more difficult because man being primarily a creature of mental Prakriti identifies himself with the movements of his mind and cannot at once dissociate himself and stand free from the swirl and eddies of the mind whirlpool. It is comparatively easy for him to put a control on his body, at least on a certain part of its movements; it is less easy but still very possible after a struggle to put a mental control on his vital impulsions and desires; but to sit like the Tantric yogi on the river, above the whirlpool of his thoughts, is less facile. Nevertheless, it can be done; all developed mental men, those who get beyond the average, have in one way or other or at least at certain times and for certain purposes to separate the two parts of the mind, the active part which is a factory of thoughts and the quiet masterful part which is at once a Witness and a Will, observing them, judging, rejecting, eliminating, accepting, ordering corrections and changes, the Master in the House of Mind, capable of self-empire, samrajya.

The yogi goes still farther; he is not only a master there, but even while in mind in a way, he gets out of it as it were, and stands above or quite back from it and free. For him the image of the factory of thoughts is no longer quite valid; for he sees that thoughts come from outside, from the universal Mind or universal Nature, sometimes formed and distinct, sometimes unformed and then they are given shape somewhere in us. The principal business of our mind is either a response of acceptance or a refusal to these thought-waves (as also vital waves, subtle physical energy waves) or this giving a personal-mental form to thought-stuff (or vital movements) from the environing Nature-Force.

The possibilities of the mental being are not limited, it can be the free Witness and Master in its own house. A progressive freedom and mastery of one's mind is perfectly within the possibilities of anyone who has the faith and the will to undertake it.
